According to certified relationship and intimacy coach Tina Laws, this 'statistical curse' is far from a coincidence.'That 13-year milestone is a major relational tipping point,' she told The Daily Mail. 'By year 13, you are hitting a heavy convergence of life stages. When couples stumble at this stage, it’s rarely because of one sudden explosion. It’s the slow burn of cumulative pressure.'The person you committed to a decade and a half ago has grown, changed, and navigated massive career shifts. If you haven't intentionally grown, you wake up realizing you've drifted into parallel lives.'Read on to discover which of your favourite celebrities have called it quits on their relationships after 13 years, and how to avoid falling victim to the same fate...Cher Lloyd and Craig Monk Most recently, singer Cher Lloyd announced she had split from her husband Craig Monk after 13 years of marriage The singer, 32, had shared a photo of her ring-free hand with her 2.6 million Instagram followers on Monday, saying her ring was 'in the bin'On Monday, Cher Lloyd announced she had split from her hairdresser husband of 13 years Craig Monk by posting a ring-free hand to her 2.6million Instagram followers.

My gut feeling. My intuition. Super symbolic dream. The vibe I got'.One of the more poignant videos shared by Cher, was a video with a voiceover saying: 'I'll buy you whatever you want', with the response: 'No you can't'.An accompanying caption read: 'What happened to old-school love? When trust came naturally, loyalty meant something, and people weren’t afraid to genuinely care for each other.'According to Kennedy MacDonald, relationship expert and founder of Female Focused Therapy, the 13-year mark is a 'particularly demanding stage of a couple's relationship'. 'By this point, the intensity and novelty of early romance has been replaced by real life - work pressures, parenting, financial commitments and running a family.'The 13-year mark can often see relationships break down as 'couples have spent years working as a team, but have come to the point where they’ve stopped relating to each other as romantic partners'.She added that couples who have been together for a long period of time 'are not necessarily those that never struggle'. 'They’re the ones who are willing to recognise what needs to happen for the relationship to evolve. What worked in the first 5 years may no longer work after 13.'Tom Brady and Gisele Bundchen Fox Sports analyst and seven-time Super Bowl winning quarterback called it time on his 13-year marriage with Brazilian supermodel Gisele Bundchen in 2022Fox Sports analyst and seven-time Super Bowl winning quarterback called it time on his 13-year marriage with Brazilian supermodel Gisele Bundchen in 2022.Tom and Gisele shared the news of their divorce with a gushing public announcement on social media. The NFL star wrote: 'In recent days, my wife and I finalized our divorce from one another after 13 years of marriage. We arrived at this decision amicably and with gratitude for the time we spent together.'Tom and Gisele's announcement of their split came after weeks of speculation that their marriage was on the rocks - with many rumors suggesting that the tension between the pair was caused by the NFL player's shock decision to reverse his retirement plans and return to the Tampa Bay Buccaneers for another season.The end of Tom's marriage came after he faced pressure from Gisele to give up the sport after he initially announced his retirement after the 2021 season.In the midst of the season, Gisele filed for divorce - ending their marriage after 13 years.Three years after splitting from Tom, Gisele married fiance Joaquim Valente on December 3.The wedding came shortly after the Brazilian supermodel and Valente, a jiu-jitsu instructor, welcomed their first child together, a baby boy. The pair reportedly began seeing each other in the midst of her divorce from Tom.Ms MacDonald explained that by 13 years into a relationship, couples can often begin 'reassessing their own identity'. 'They might be asking themselves: “Is this the life I actually want?” or “Who am I outside this marriage, my career or my role as a parent?”,' she added.'This can be particularly powerful in midlife, when combined with hormonal changes, parents getting older, career dissatisfaction or kids going off to Uni or becoming more independent.'Isla Fisher and Sacha Baron Cohen After 13 years of marriage, Isla Fisher and Sacha Baron Cohen went their separate ways in 2023, before their divorce was eventually finalised in June 2025 (pictured together in 2017)After 13 years of marriage, Isla Fisher and Sacha Baron Cohen went their separate ways in 2023, before their divorce was eventually finalised in June 2025.The Australian actress, 49 and Sacha mutually announced the end of their 14-year marriage at the end of 2023 with the divorce finalised this past June.Their statement read: 'After a long tennis match lasting over 20 years, we are finally putting our racquets down.'In 2023 we jointly filed to end our marriage. We have always prioritized our privacy and have been quietly working through this change.'We forever share in our devotion and love for our children. We sincerely appreciate your respecting our family's wish for privacy.'The couple first met back in 2001 and tied the knot in 2010. Ms MacDonald noted that after more than a decade together, the keys to a successful marriage can vastly change. 'Couples need to become curious about each other again, talk honestly about resentment before it turns into contempt and deliberately create time together that is not focused on kids or household admin,' she added.'Affection, sex and emotional intimacy need to be consciously rebuilt rather than expecting it to happen naturally.'Gwen Stefani and Gavin Rossdale Gwen Stefani and Bush frontman Gavin Rossdale announced their divorce in August 2015 after 13 years of marriage and 20 years togetherGwen Stefani and Bush frontman Gavin Rossdale announced their divorce in August 2015 after 13 years of marriage and 20 years together. The 56-year-old singer shares three sons Kingston, 18, Zuma, 16, and Apollo, 10, with Gavin - who she divorced in 2015.At the time of their divorce she accused Gavin of adultery and reports swirled afterwards that Gavin had had a three-year affair with Mindy Mann who was their family nanny.She has since remarried to the country music star Blake Shelton while he is now in a relationship with singer girlfriend Xhoana X.Last year, Gavin revealed that 30 Rock Star Jack McBrayer helped him 'raise' his kids after his divorce from Gwen.Reflecting on the house they had in Los Angeles, he said: 'It was such an exciting time. I was there for a number of years when we were just together, when we got married, we had our first kid there.'Gwen did a beautiful job on the nursery. That house has fantastic memories. We used to have amazing new year's eve parties every year. We never knew what to do, so it was easier to make the party come to us. Fantastic times.'That was right at the height of everything really fun work-wise, it was really a great time for us. So I have a great memory of that house. Beautiful time.'While a long-term relationship comes with a strong sense of comfortability and familiarity, Ms MacDonald stressed that it can also lead to couples that 'stop discussing their emotional needs' as 'conversations feel repetitive or pointless'.'Eventually, they become more like housemates or co-parents than partners,' she added.Ms Laws stressed that 'familiarity breeds emotional distance', and noted: 'Couples trade intentional, high-priority intimacy for operational efficiency—running the household and the business like a joint venture instead of a romance.'Reese Witherspoon and Jim Toth Reese Witherspoon and talent agent Jim Toth finalised their divorce in August 2023, just shortly before their 13th wedding anniversary. Pictured: Reese and Jim in January 2020Reese Witherspoon and talent agent Jim Toth finalised their divorce in August 2023, just shortly before their 13th wedding anniversary.The pair cited irreconcilable differences as the reason behind their split in court documents.Reese and Jim's divorce documents were filed in Nashville, Tennessee, where the couple lives with their son.The documents reveal the couple agreed to a prenuptial agreement in March 2011.Shortly after the divorce was made public, Reese opened up about how she was going through a 'vulnerable time' amid the divorce. At the time, the couple wrote to their fans: 'We have some personal news to share … It is with a great deal of care and consideration that we have made the difficult decision to divorce.'We have enjoyed so many wonderful years together and are moving forward with deep love, kindness and mutual respect for everything we have created together.'The former pair emphasized that their 'biggest priority' is their son Tennessee.Ms MacDonald noted that while a couple can share many joyous years together, 'sometimes the old version no longer fits'. She explained that while not every difficult period is 'proof that a relationship is over', sometimes it is best to acknowledge when to go your separate ways. Cat Deeley and Patrick Kielty Presenter Cat Deeley announced her divorce from husband Patrick Kielty in July last year, 12 years since their wedding dayPresenter Cat Deeley announced her divorce from husband Patrick Kielty in July last year, 12 years since their wedding day.The couple sparked speculation they had split when Cat was absent from Patrick's mother's funeral in Ireland in March last year.Patrick and Cat stressed that 'no other party' was involved in the disintegration of their relationship which is believed to have been privately finalised at the start of the year, before going public months later.In a joint statement the couple said: 'We have taken the decision to end our marriage and are now separated. There is no other party involved.'We will continue to be united as loving parents to our children and would therefore kindly ask for our family privacy to be respected. There will be no further comment.'The Daily Mail previously revealed how Patrick's family were seething over Cat's failure to attend his beloved mother's funeral – and say they knew at that moment their marriage was over for good.A spokesperson for Cat told the Daily Mail at the time: 'Cat remained at home to be there for her two young children before and after school on this very sad day.'According to divorce lawyer Ana Vilhete, 'trouble at the 13-year mark is unfortunately more common than you'd think'. He added: 'I'm seeing more people grow fearful of ending the decade feeling just as unhappy as they were in 2020.' To avoid falling victim to the 13-year curse, Ms Laws suggested 'leaning into conscious reinvention'. 'Make your marriage the priority and the foundation of your life, not just something that fits into the margins after your career and kids,' she added.'What worked for the last 13 years won't automatically carry you through the next 13. Sit down and consciously design what this next era looks like together.'
