Altidore has been a bit of a fixture at Stephens' tennis matches in recent years, with the two Florida natives reportedly having dated since 2016. The U.S. international soccer star was in the stands to watch Stephens in the semifinal of the 2017 US Open, but couldn't be there for the final because he was playing a game himself.

Altidore's mother informed him that Stephens had indeed won the US Open at halftime of his game in which he scored twice in a 4-0 win against San Jose.

In addition to winning a Grand Slam title in 2017, Stephens was the 2018 French Open runner-up and a member of the 2017 champion U.S. Fed Cup team.

The 26-year-old American currently is ranked No. 8 in the world.

The 29-year-old Altidore has scored 41 goals in 110 international appearances since his U.S. national team debut in 2007. Altidore has been with Toronto FC in Major League Soccer since 2015.
