With the U.S. Open in full swing, stars are making their way to Queens, N.Y. to get a glimpse of tennis superstars smashing their way to a new slam title.

This year’s tournament boasts an extra large number of celebs possibly because the world’s 20th seed Andy Roddick announced that he’s retiring after the tournament.

So who was spotted out in the stand cheering him on for his final farewell?

Modern Family’s Sofia Vergara, Hitch actress Eva Longoria, and Mean Girls star Amanda Seyfried were seen in the stands rooting for Roddick and other tennis stars.

And they weren’t shy to show their support — throwing their hands in the air and making noise for the star.

During the press conference to announce his decision to retire, Roddick remembered how he felt at the All-England club after losing to David Ferrer in the third round at Wimbledon.

“Walking off at Wimbledon I felt like I knew. I couldn’t imagine myself being there another year.”

He added, “I think I wanted an opportunity to say goodbye to people, as well.”
