Jessie J gets behind the mic to record “Grease Is The Word” in this new video for Grease: Live.

The entire cast — Aaron Tveit, Julianne Hough, Carlos PenaVega, Vanessa Hudgens, David Del Rio, Andrew Call, Jordan Fisher, Kether Donohue, Keke Palmer and Carly Rae Jepsen — joined her in the studio for the track, which is the first song of the musical.

“There’s no pressure like being the first one on stage,” Jessie shared. “I love that rush of the nerves that I’m going to get. I just feel really honored and really lucky that I’ve been asked to experience something like this.”

She added, “It’s a massive moment for me and I’m very lucky that I’m getting to share it with such amazing people.”

Grease: Live premieres Sunday, January 31st @ 8PM ET/PT on Fox.
