Whoa! Julianne Hough Bares Cleavage in Plunging Dress

Looks like someone is ready to cut loose...and not just on the dance floor.

While promoting her new flick "Footloose," Julianne Hough has rocked several chic outfits including a red top and matching shorts, a sparkly midnight blue dress and a tuxedo-inspired number.

VOTE: Which look was hotter on Julianne?

And on Monday night, the 23-year-old dancer-turned-actress, went for her sexiest, most daring look yet at the Yahoo Hollywood Movie Awards.

Hough wowed in a plunging gold beaded cocktail dress straight off designer Naeem Khan's Spring 2012 runway. In addition to showing off tons of cleavage, the hot frock was also backless.

The former "Dancing With the Stars" pro recently revealed how she maintains her killer physique. "I vary my workouts every day because, otherwise, I get bored," she said in the November issue of Self magazine. "I always try to run for 20 to 40 minutes on the beach first. Six days a week is fantastic, but four is great too."
