Alex & Sierra were an American indie folk-pop duo based in Orlando, Florida who won season 3 of The X Factor USA.
They were a part of the Groups catagory, mentored by Simon Cowell.
In this part of the competition, Alex & Sierra took on the John Travolta/Olivia Newton-John classic "You're The One That I Want" from the 1978 musical film Grease.
The judges praised them for putting their own twist on the song.
