Alex and Sierra Reinvent Grease Song on The X Factor [Video]
I've got chills and they're multiplying. And I'm losing control over this version of "You're the One That I Want" from Grease. Trust me! You have never heard that song in this way before. Check out how X Factor duo Alex and Sierra performed the John Travolta/Olivia Newton-John classic.
With this performance, Alex and Sierra earned a spot in Simon Cowell's final four. He is mentoring the Groups category this season and has a powerful one-two punch with Alex and Sierra. They're unique, inventive and a blast to watch.
The X Factor airs Wednesdays and Thursdays on Fox.
