'X Factor' Finale Night 1: Simon Says, "I Can't Call It"

Never one to be accused of being at a loss for (critical) words, Simon Cowell only had nice things to say about all three finalists (Fifth Harmony, Tate Stevens and Carly Rose Sonenclar) on night 1 of the X Factor season 2 finale.

"I can't call it," Simon said, while 13-year-old Carly urged fans to vote.

Whoever wins tonight, Carly and Fifth Harmony's Camila Cabello, 15, are in for a thrill.

X Factor U.K. royalty One Direction (along with Pitbull) will be performing, and Carly and Camila both revealed they have a major crush on Harry Styles. But really, who doesn't?
