Serena Williams is off the court and into the dance studio for a lingerie campaign for sportswear brand Berlei.
The tennis champion shared a clip from the campaign with the motivational motto Do it For Yourself on her Instagram page, and added the caption: "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?"
Serena can be seen dancing and spiraling across the floor to a cover of Billy Idol's 'Dancing with Myself' by The Donnas in a sports bra, black underwear and throwback '80s leg-warmers in the video which has garnered over 500,000 views.
The 34-year-old sports star - who is also brand ambassador for Berlei - revealed that the campaign centres on "celebrating female strength, power and beauty." She custom designs her bras in coordinated colours ahead of every big game.
Meanwhile, Serena recently announced her engagement to Reddit co-founder Alexis Ohanian after 15 months of dating.
