'The X Factor': Watch Justin Bieber and Others Perform in the Finale (VIDEO)

If you happened to miss last night's finale of "The X Factor" (or just decided to skip the first hour and 50 minutes and tune in for the end), you missed out on a bunch of big performances from celebrities, with some of the former finalists mixed in. Lucky for you, we have all the videos compiled for you in a neat little package, like it was Christmas or something.

The show started off with everyone from the Top 12 singing "Edge of Glory" by Lady Gaga, including groups Lakoda Rayne, The Stereo Hogzz and InTENsity, Over 30s Stacey Francis, Josh Krajcik and LeRoy Bell, Boys Marcus Canty, Chris Rene and Astro, and Girls Melanie Amaro, Drew and Rachel Crow. Watch closely to see a shot of the cast of "New Girl" looking enthused.

Later in the show, Justin Bieber took the stage with Stevie Wonder to perform a couple of Christmas songs, and was joined by none other than Drew, who cited Bieber as her idol back at her audition. If you want to see a girl in a state of pure joy, just watch that video.

Leona Lewis came out shortly after to perform an odd tribute to eliminated contestants that played a bit more like an In Memoriam segment. Rather than sing one of her own songs, Lewis sang "Run" by Snow Patrol.

Astro got the chance to rap with one of the biggest stars out there as he joined 50 Cent on stage. The two were also joined by members of the LA Lakers, who teamed up with 50 Cent for a charity drive.

And finally, just before the winner was announced, Ne-Yo and Pitbull were joined by fourth place runner-up (against all odds) Marcus Canty.
