THE X FACTOR Reveals Top Four Acts

The Top Four acts on THE X FACTOR are Paulina Rubio's Boys - Carlito Olivero; Kelly Rowland's Over 25s - Jeff Gutt; and Simon Cowell's Groups - Alex & Sierra and Restless Road.

In another LIVE results show, Ellona Santiago and Rion Paige, Demi Lovato's last two Girls, were eliminated on THE X FACTOR. Tonight, host Mario Lopez announced early in the broadcast that Santiago had the fewest votes following last night's performance show, and she was eliminated immediately. Paige and Carlito Olivero received the next fewest votes. The judges - Simon Cowell, Demi Lovato, Kelly Rowland and Paulina Rubio - listened to the two acts compete in "The Final Showdown" sing-off and ultimately, Paige was sent home. Earlier in the show, Emblem3 and Little Mix returned to THE X FACTOR stage to perform.

THE X FACTOR continues on Wednesday, Dec. 11 (8:00-10:00 PM ET live/PT tape-delayed), as the Top Four acts battle it out for America's votes and a chance to compete in the Finale. On Thursday, Dec. 12 (8:00-9:00 PM ET live/PT tape-delayed), another act will be sent home, and Jennifer Nettles and Enrique Iglesias will perform.
