EXCLUSIVE: Rumer Willis Reveals Her Secret to Winning 'Dancing With the Stars,' Would Love to Return as a Gues

As the season 20 champion of Dancing With the Stars, Rumer Willis has a word of advice for this season’s contestants: enjoy yourself!

“You're doing something in a very accelerated pace, and when you're in it, the concept of time is not really there,” Willis tells ET. “Just really take a moment and enjoy it. Enjoy the experience, enjoy learning and the challenges, all of it.”

Willis, who took home the mirror ball trophy with pro partner Valentin Chmerkovskiy in spring 2015, is currently starring as Andy Sachs in The Unauthorized Musical Parody of The Devil Wears Prada at the Rockwell Table & Stage in Los Angeles. The 27-year-old actress says she misses the challenge of the DWTS competition, but continues to pursue projects that force her out of her comfort zone.

“I think just being challenged every week to try something new and not to just challenge your body but challenge your mind, that's kind of why I like doing new things and even coming back and doing a show like this,” she explains. “I love being around people who are talented and it makes me want to step up my own game.”

Willis also opened up about her experience with Chmerkovskiy, as the relationship between star and pro is crucial to DWTS success. Former DWTS pro Cheryl Burke recently dished about her tumultuous time dancing with Beverly Hills, 90210 star Ian Ziering, saying she wanted to “slit her wrists” while competing with him.

Burke has since apologized for her comments, though Willis says her experience with her own pro partner was very different.

“I don't know if I was just lucky or [what], but you really have to come into it with the headspace of what you're wanting,” she shares. “If you come in with a good attitude and ready to work and participate and make it the best situation possible for everybody included, then I think you can't really fail.”

The actress also insists she would “for sure” be willing to return for an all-star round of DWTS, or even as a guest judge.

“I would love that!” she gushes. “It's such a cool world and I've always been a huge fan of dance. To be able to do that again would be amazing.”
