Julianne Hough Turns @$$ Kicking Beach Babe (PHOTOS)

Julianne's Bikini Body
See the body 'Dancing' made 'Rock' hard.
Watch out for Julianne Hough. She’s gone from Dancing with the Stars champ (twice) to country singer to actress — and while she’s always been a “knockout,” now she’s ready to bring the smackdown!

The 22-year-old proved she’s ready to rumble as she punched it out on some rocks overlooking the beach in Miami, Florida, with her trainer. The gut-busting workout was followed by a jog back home.

The intense training could very well be preparation for her upcoming role in Rock of Ages, in which she will use all her skills to act, dance and sing alongside some Hollywood heavyweights. In the meantime, she’s been busy buddying up to some of her castmates, including newcomer Diego Boneta — and we don’t blame her for getting close to this hottie. Although she and Ryan Seacrest appear to be going strong, it never hurts to have good looking friends! (Find out more about Diego here)

Julianne and the Broadway star have been spotted out together for dinner and a movie while in Miami, where Tom Cruise and the entire Rock gang has gathered to get pre-production underway.

Should her boyfriend be jealous of her time with her newfound friend? Doubt it! Ryan actually joined Julianne in the sunny city just a few weeks ago.
