It’s almost time to give your heart a break, X Factor viewers. But first, things are going to get super emotional as judges and American voters anoint the Season 2 winner. Will it be Carly Rose Sonenclar, Tate Stevens, or Fifth Harmony? From the looks sound of the live finale performances on December 19, 2012, Fifth Harmony took the lead — with the help of one very famous pop star: judge Demi Lovato.

Demi took the stage with Simon Cowell’s girl group to sing “Give Your Heart a Break.” Simon’s heart must’ve grew three sizes during the song, as he could not stop gushing about his onetime rival’s performance. “Demi Lovato, you were sensational,” Simon said, seeming to surprise even himself, adding, “That was pop perfection.” (Simon obviously forgot he was sitting next to Britney Spears).

Simon then cheekily quipped, “Anytime you want to join this group, Demi...” Uh, yeah, let’s not, Simon. They’ve been through enough name changes. We’re not sure we could take “Sixth Harmony” too. Love you like a sister, tho!
