Brad Pitt. Before ascending to Hollywood superstardom, Brad was on the tennis team at Kickapoo High School in his hometown of Springfield, Missouri. We're not sure how Brangelina would fair on the courts now, though.

Kaley Cuoco. She's now known for her role as Penny on The Big Bang Theory, but growing up, she was a regionally ranked amateur tennis player.

Charlie Ward. An all-around superstud athlete, Ward won the Heisman Trophy while playing football at Florida State University. He ultimately decided to play professional basketball in the NBA, but he was also a star junior tennis player before he had to quit to make time for the other sports. It's nice to have options, isn't it?

Gavin Rossdale. Rossdale is the lead singer of the '90s rock band, Bush, and an avid tennis player. (Yeah, we haven't heard of them either.) He's probably best known nowadays as the baby daddy of Gwen Stefani's brood—the couple has four kids together and can often be seen in the grandstands at major tennis tournaments cheering on their buddy, Roger Federer.
