The two star athletes are officially dating.
Caroline Wozniacki and David Lee are social media official.
The star tennis player and the 34-year-old two-time NBA All-Star confirmed their relationship on Instagram.
Wozniacki took to Instagram on Sunday night.
"Having the best time with my love!" she wrote.
There had been some obvious signs of the relationship in previous weeks.
Wozniacki's brother spoke to a Danish tabloid, also confirming the relationship.
“I think it’s really good. … He’s a clever guy, also considerate. … And he is obviously very athletic as a professional basketball player,” he said.
Wozniacki previously dated star golfer Rory McIlroy.
