It's the last week of Season 3 Live Shows before the grand finale of December 18 and 19 so we're expecting the fiercest night of competition yet. Four acts remain in The X Factor — Jeff Gutt, Alex & Sierra, Carlito Olivero, and Restless Road — and each brings something new and exciting to the table.

With only three judges still in the running for Season 3 bragging rights (that would be Simon Cowell, Paulina Rubio, and Kelly Rowland) the trash talk might also get heated over at the judges's table. Demi Lovato, you okay playing referee? 

For tonight's (December 4) show, each contestant will perform three songs including a head-to-head duet against a rival act. Talk about tension!

For a reminder on where the teams currently stand, take a look below. Already know who's taking home the title next week, or still waiting for a winner to emerge? Share your thoughts in the comments below.
