Check out the abs on Sandy and Rizzo!
Vanessa Hudgens and Julianne Hough are gearing up for their performances in FOX's Grease: Live on Jan. 31, and in anticipation, posed in sexy black and white crop tops that perfectly match their characters' personalities.
Hudgens is taking on the role of bad girl Rizzo, while Hough will portray the virtuous Sandra Dee. The Dancing With the Stars judge captioned the pic with a devil and angel emoji.
"I love everything about a live show and the adrenaline that you get from doing something live," Hough said in a behind-the-scenes clip from the production. "Then on top of that it's Grease and it's such an iconic show. I think this feels like a dream for most of us."

Hudgens is also pumped about playing her iconic character. "As soon as I put my costume on I started to find my Rizzo already," the High School Musical star said. "It's going to be a good time."
Hough told ET that Olivia Newton John -- who played Sandra Dee in the 1978 Grease movie -- gave the 27-year-old star her blessing to take on the beloved role. Hough recalled, "She was, like, 'Oh my gosh! You're going to be great! They couldn't have picked a better Sandy.'"
