Sources told Us Weekly that the relationship is new and that DeChambeau and Demaiter are “very happy” together. The romance gained attention after Demaiter appeared at LIV Golf New York wearing a Crushers GC hat, the team DeChambeau captains.The couple has kept their relationship private so far, but Demaiter is expected to continue supporting DeChambeau at LIV Golf events. That could include LIV Golf Indianapolis, which begins Thursday, August 20, at The Club at Chatham Hills. For DeChambeau, the relationship adds another layer of attention around a golfer whose profile extends well beyond the course.Who is Bryson DeChambeau’s girlfriend Mikayla Demaiter?Mikayla Demaiter is a model and social media personality who previously played hockey as a goalie for the Bluewater Hawks in the Provincial Women’s Hockey League. Her hockey career ended at 19 after an injury, but the sport remains part of her public image. She still appears in hockey gear for photo shoots and regularly references her time on the ice.Demaiter has built a substantial following since moving into modeling and social media. She has more than 3 million followers on Instagram and about 2.7 million on TikTok, giving her a significant audience of her own. Her online presence has also kept her connection to hockey visible, even after she was forced to retire from competitive play.Her personality away from the golf course is reflected in some of her posts. In May, Demaiter wrote on Instagram, “Everyone asks me why i chose to be a goalie, and the answer is simple, there’s nothing i love more than being number one.” In November 2024, she posted a video skating in full pads with the caption, “guess you could say i’m a keeper…”How did DeChambeau and Demaiter spark dating rumors?The first major public clue came at LIV Golf New York earlier this month. Demaiter attended the event with a guest pass and was seen wearing a Crushers GC hat, linking her appearance directly to DeChambeau’s LIV team. That sighting fueled speculation before the relationship was confirmed by Us Weekly.The confirmation followed on Wednesday, August 19. According to an insider quoted by Us Weekly, “They are both pretty private when it comes to relationships,” while adding that they are “very happy” right now. Demaiter is expected to keep appearing at DeChambeau’s events, making LIV Golf a likely setting for more public glimpses of the new couple.DeChambeau and Demaiter could make more public appearances togetherDeChambeau’s golf schedule could give Demaiter more opportunities to support him publicly. He is set to compete at LIV Golf Indianapolis this week, while he also announced that he will return to the DP World Tour at the Nedbank Golf Challenge in South Africa in December. “I can’t wait,” DeChambeau said in a social media video on August 17. “I’m honored to be a part of it.”The golfer also remains a high-profile figure away from competition. Last year, DeChambeau appeared in Adam Sandler’s Happy Gilmore 2 and was selected to chair President Donald Trump’s Council on Sports, Fitness and Nutrition. His growing profile means his new relationship with Demaiter is likely to attract attention well outside LIV Golf. Fans are expecting the couple’s public appearances.
