The young tennis star is dating another professional athlete.
Sloane Stephens is the breakout star of the U.S. Open this year.
The 24-year-old women's tennis stud has recovered from an injury and a brutally low world ranking to reach the finals of the season's final Grand Slam.
Stephens knocked off Venus Williams in an epic three-set match on Thursday night.
In attendance at the match was Stephens' boyfriend - Jozy Altidore, the U.S. soccer star.
Altidore has been in attendance for several of her matches.
Stephens is set to play in the final on Saturday against fellow American Madison Keys at 4 p.m. E.T.
