X Factor's back and starting its second week of Live Shows with a major bang: One of the Top 13 goes home tonight! Why? Well, there was a slight tech issue last week that meant no one went home, keeping the remaining 13 contestants on pins and needles all weekend as they wondered if they'd ever get a chance to perform their 1980s numbers. 

Once the elimination is over — we hope it's quick and fast like ripping off a Band-Aid — the Top 12 will take to the stage and work to earn our votes. How do we do that again? We've got the 411. Let's just hope the telephone numbers are correct this week...

Here's a quick refresher on which judge has which team:

Boys (Paulina Rubio)Carlito Olivero, Tim Olstad, Josh Levi (wildcard). Sadly, Carlos Guevara was sent home before he got a chance to perform

Girls (Demi Lovato): Ellona Santiago, Rion Paige, Khaya Cohen

Over 25s (Kelly Rowland)Rachel Potter, Jeff Gutt, Lillie McCloud

Groups (Simon Cowell)Restless RoadAlex & SierraSweet Suspense
