VIDEO : Rumer Willis Flaunts Killer Bikini Bod During Dancing With the Stars Tour--and the Shirtless

It looks like Rumer Willis is having some fun on tour! The brunette beauty and recent mirror-ball trophy winner showed off her killer bikini bod while on the Dancing With the Stars tour, when she took a little swim break with her equally attractive pals. "The boys are back in town... @keo_motsepe and @alanbersten," she captioned the photo, which shows her strutting a black string bikini while the other shirtless two showed off their abs. While there's no denying Willis' enviable bod, we can't help but mention that her scenery isn't too shabby, either.
