“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!
