'Grease: Live!' Star Julianne Hough Has Olivia Newton-John's Blessing

Julianne Hough and her Grease: Live! cast mates Vanessa Hudgens, Carlos PenaVega and Aaron Tveit stop by AOL Build to chat about their upcoming production on Monday (January 18) in New York City.

The 27-year-old actress, who is playing Sandy, told the audience that the original movie’s star Olivia Newton-John gave Julianne her blessing for the role.

“It’s a little daunting. I mean, those are some big shoes to fill,” she said. “But Olivia has been amazing. I got to meet her a couple months ago and she kind of gave me her blessing, which was a huge weight off my shoulders, because all I want to do is make her proud.”
