Will Lionel Messi attend Cristiano Ronaldo's wedding (Instagram and Getty Images)Cristiano Ronaldo's wedding to Georgina Rodriguez is shaping up to be the most talked-about social event of 2026 and not entirely for the right reasons. A leaked invitation tying the ceremony to a specific date and venue in Portugal set off a wave of speculation that Spanish media quickly poured cold water on. Yet the noise refuses to die down, and one name keeps surfacing above all others on the rumoured guest list: Lionel Messi. Whether the Argentine actually shows up is another matter entirely.Will Lionel Messi attend Cristiano Ronaldo's wedding and what are the bookmakers saying?William Hill have opened a market on who will actually show up in Madeira, and the odds make for interesting reading. Rio Ferdinand is the overwhelming favourite at 1/6, with Sir Alex Ferguson at 4/7 and Wayne Rooney at 4/5. All three have obvious connections to Ronaldo's Manchester United years. Zinedine Zidane is 1/2, while Vinicius Junior, Kylian Mbappe and Neymar are each priced at 2/1.Lionel Messi sits at 2/1 as well -- the same price as Mbappe and Vinicius -- which tells you something about how seriously the market is taking his inclusion. The leaked guest list circulating online does feature his name, alongside Rihanna, Drake, Jennifer Lopez, Travis Scott and Vin Diesel. But the more credible versions of the list do not. Reporting notes that Messi's name does not appear on the verified guest list, and that his attendance is considered unlikely.The two never shared a dressing room. Their rivalry across nearly two decades of La Liga El Clasicos and Ballon d'Or ceremonies was extraordinary, but personal warmth was always harder to confirm than professional respect. There is one angle that keeps the speculation alive, though: Georgina Rodriguez is said to have a genuine friendship with Messi's wife, Antonela Roccuzzo. Whether that social connection translates into a wedding invitation is something only Ronaldo's inner circle knows for certain.William Hill spokesperson Lee Phelps summed up the broader intrigue well: "The real question is whether CR7's oldest rival turns up. It's not just football royalty in the running -- names like Khabib, Piers Morgan and IShowSpeed show just how far Ronaldo's circle extends."Roy Keane, famously not among Ronaldo's most devoted admirers, is priced at 10/1. Conor McGregor is 5/1. The list goes wide and deep, which says as much about Ronaldo's global reach as it does about the wedding itself. But amid the Rihanna rumours and the Mbappe speculation, it is the Messi question that everyone keeps coming back to. If he does walk through that cathedral door in Funchal, it will be the most photographed moment in football since the World Cup final and that might be underselling it.Is the leaked Ronaldo wedding invitation real and what does it actually say?The invitation that sent the internet into overdrive named the Quinta da Regaleira palace in Sintra as the venue, set a date of August 1, and asked guests to dress in black. It was dramatic, specific, and almost immediately disputed. Spanish media outlets rejected the date, and the palace itself kept its doors open to the public that weekend -- hardly the behaviour of a venue hosting a globally watched private ceremony.Since then, attention has shifted to Madeira, where Ronaldo was born and raised. Reports from Portugal now point to Funchal Cathedral as the likely venue for the ceremony, with the Savoy Palace Hotel -- two floors reportedly reserved -- earmarked for the reception. Speculation intensified further after guests are said to have been told that sections of the hotel would be closed for a private event. The date doing the rounds is August 8, though neither Ronaldo nor Georgina has confirmed anything publicly.Ronaldo himself has spoken openly about the wedding, including to journalist Piers Morgan, saying he wanted to walk down the aisle after winning the World Cup. Portugal's exit at the last 16 against Spain changed that particular plan, but it clearly has not changed the timeline by much.
