Hump day will never be the same.
On Wednesday, Berlei released a new sexy ad featuring Serena Williams dancing by herself in lingerie to a cover of Billy Idol's "Dancing With Myself."
The ad for the Australian intimates brand was shared along with the hashtag #DoItYourself, which holds special meaning for the newly engaged tennis legend.

"To me, 'Do It for Yourself' is really standing up for yourself and what you believe in and just doing it," Williams, 35, said in a behind-the-scenes video. "I always say there's going to be so many people who are not going to believe in you and try to hold you back from your dreams, but I believe that it's really so important to do everything in your life for you. And I think ultimately you get the best results that way."
The 60-second commercial shows that Williams' talents clearly extend beyond the tennis court, and she opened up about her passion for dance in an Instagram post.
"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," she wrote. "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?"
