There were stars all over on Finals Day at the US Open, like Ne-Yo, who sang at the opening ceremony.
And WTA legend Monica Seles, who posed for a photo with the finalists at the net before the final.
It was then time for Serena Williams and Victoria Azarenka to duke it out on Arthur Ashe Stadium...
But the celeb sightings didn't stop there - Ricky Martin and Eva Longoria were in the Williams box.
Actress Sarah Jessica Parker, best known for Sex And The City, also watched on from the stands.
Actor Hugh Jackman, best known for his role as Wolverine in the X-Men films, was also watching on.
Two in one here - Amanda Seyfried of Mean Girls fame and Jesse Metcalfe of Desperate Housewives fame.
Singer Gladys Knight, nicknamed the 'Empress Of Soul', along with fashion model Selita Ebanks.
Randy Jackson of American Idol fame with one of his former pupils on the show - Constantine Maroulis.
Allyson Felix, a four-time Olympic gold medal-winning sprinter, including the 200 meters in London.
And the most revered of all the celebs, the former President Of The United States, Bill Clinton.
All of them watched on as Serena Williams completed a 75 67(6) 61 victory against Victoria Azarenka.
Williams is now 13-3 lifetime against Azarenka, but many, many of those have been very tight.
Williams won her fifth US Open title and 17th Grand Slam title, and a record $3.6-million payout.
Despite the head-to-head disparity, Williams and Azarenka are very good friends on the tour.
And there was a lot of love as one American icon met - and congratulated - another American icon.
Clinton also met Williams' beloved little pooch, Christopher 'Chip' Rafael Nadal, during the visit.
And he met another American icon - seven-time Grand Slam champion and former No.1 Venus Williams.
Also in the player tunnel, Williams posed with the celebs from her player box, Longoria and Martin.
Chip sniffed the trophy - is the man he was named after on the verge of his own US Open trophy?
