Dustin Johnson issued a statement via Twitter amid growing questions about his relationship with fiancée Paulina Gretzky.

“Every relationship goes through its ups and downs, but most importantly, we love each other very much and are committed to being a family,” Johnson wrote. “Thank you for your love and support.”

Last weekend social media observers noticed Gretzky had deleted all photos of Johnson from her Instagram account, fuelling speculation that one of the sport’s most recognised couples was on the verge of a split. Gretzky and Johnson have been engaged since 2013, and have two sons together.

Johnson’s representatives told Golf Digest that Johnson had no follow-up statement on the matter.

Johnson is scheduled to play in the US PGA Tour’s season-finale Tour Championship next week at East Lake Golf Club, along with representing the United States in the Ryder Cup a week later.

Gretzky, who is a model, singer, celebutante and daugher of ice hockey Hall of Famer Wayne Gretzky, is yet to issue a comment.
