Hollywood stars, a Grammy-award winning artist and a world-famous tennis pro all came together in Austin Friday night for one very important reason: helping Central Texas kids.

The annual Andy Roddick Foundation at the ACL Moody Theater has raised more than $5.5 million for after-school and summer programs for Austin-area students.

Andy Roddick, joined by his wife Brooklyn Decker on the red carpet in Downtown Austin, explained to KVUE why this foundation is so important to him.

"These kids are young, they don't know that I ever did anything in the sports world or anything else," said Roddick. "When the parents can drop them off, know that they're in a good place and have that piece of mind, go to work, pick them up and at the end of the day we've not only maintained but add some value, that's the goal. And the fact the kids say it's fun along the way is great."

Roddick works closely with students at Pecan Springs Elementary in Northeast Austin. On Friday night, some of the students joined him at the gala: Calvin, Rosa, and Mia.

"He taught us a lot of new tennis moves," explained Calvin, dressed in a little suit and loafers.

"Calvin's the man! I mean, he came proper tonight," said Roddick.

Grammy-award winner John Legend joined by his wife, model Chrissy Teigen, flew into Austin for the foundation's annual gala. Legend's performance will directly benefit these Central Texas children.
