Brooklyn Decker and Andy Roddick
She's made a career for herself in modeling and movies, and now, Brooklyn Decker
is ready to tackle a new challenge: the stage.
Just don't ask her to sing or dance.
"I am no triple threat," Decker, 25, told PEOPLE at the 7th Annual Andy Roddick Foundation Charity Gala at the W Hotel in Austin on Friday night. "Not even a little bit. Not even a tiny smidge. At all."
Decker joined newly retired
husband Andy Roddick, 30, as well as John Legend, who performed at the event – and smiling newlyweds Matthew McConaughey
and Camila, who is expecting the couple's third child – at the event to raise money for the Andy Roddick Foundation
"I've never done any theater, but I am trying to read for a few plays and hopefully I will get something by the end of this year in New York," says Decker. "I might as well dive in head first."
But she and Roddick did oblige Legend when he called them onstage for a little slow dancing before the crowd, who helped raise over a million dollars for the foundation (including a winning $18,000 bid from the McConaugheys on a VIP all-access package for the Austin radio program The Bobby Bones Show
). Roddick plans to build a 10,000 sq-ft, eight court tennis and learning facility for kids in Austin.
"I plan to be more hands on with this foundation," Roddick told PEOPLE. "[My] decision to retire wasn't an accident. It was getting to the point that it was harder and harder to leave Austin. When I was on the road, I missed home a lot and when I was home I didn't miss the road so much, so it was a pretty easy decision for me."
Decker says Roddick's dedication to the ARF, which he launched in 2000, is part of the reason she fell for him.
"The fact that Andy does work for kids doesn't hurt when you are looking at a checklist for a guy," she says. "He loves kids, he does great things in his community."
