Why Julianne Hough Was Not Allowed to Watch ‘Grease’ in High School

“Extra’s” Mario Lopez is the first reporter on the set of "Grease Live,”, where he chatted with Julianne Hough, who is playing Sandy, the role made famous by Olivia Newton-John.

Though Hough is playing Sandy now, it was a different story in her high school days. She revealed, "I wasn't even allowed to watch ‘Grease' because it was too racy for me. I would steal it when my parents were out of the house and I'd watch it over [and over] again.”

Mario will also take part in the live production, playing host Vince Fontaine, so make sure to catch it on January 31 on FOX!
