Serena Williams has a rock hard body and isn’t afraid to show it off.

In a a new ad for Berlei underwear, the tennis champ lets her hair down a little, so to speak.

In the spot, Williams enters a dance studio and starts to move it, move it to a Billy Idol cover of “Dancing with Myself.”

She jumps around with just a bra for a top as well as stretch pants and seems to be having a blast.

The theme of the campaign is “Do It For Yourself.” It reminds us of a cross between Tom Cruise in “Risky Business” and Jennifer Beals in “Flashdance.”

On her Instagram, she explains: “Sometimes we are all so serious and we forget to have fun – and I know that’s me a lot of the time, but it’s so important to have passions in your life that are just for you. I’m so disciplined every day with my training, but when I dance it’s about letting myself go. What do you do for you? #DoItForYourself @berleiaus @berleiusa.”

The Palm Beach resident, who recently got engaged to Reddit co-founder Alexis Ohanian, is currently in Melbourne, at the Australia Open. Sister Venus is there as well, and told USA Today she was happy for her roommate.

“She’s actually getting a real life. She’s paving the way, once again, for me,” said Venus. “Maybe I’ll grow up.”

She’s also hoping to find love one day.

“You know, you can’t plan these things,” the younger Williams sibling said. “You just have to live and see what happens.”
