The judges were playing nice for most of the night, so it was up to Kitty Brucknell and Misha B to bring tension with their song-scrap. Though we wouldn't be surprised if Janet Devlin kicked off backstage as the judges continued to contradict themselves over the direction she should be taking.
Other highlights of Lady GaGa Vs Queen night included another belter from Tulisa's "little muffins" Little Mix, a fantastic if familiar Marcus Collins performance and, of course, Louis Walsh's "little Jackie Chan" clanger.
But whose X Factor dream will be smashed tonight? Will Amelia be brought back just to be kicked out again? Could it be three strikes and out for Kitty? Reality Bites is here to live-blog the results, the sing-off and the tears as Lady GaGa and One Direction pop in for some very special performances.
21.02 So that's X Factor done for another week. We're getting into the home stretch now, so it's time to start thinking about picking a winner, folks. Next week will include performances from last year's runner-up Rebecca Ferguson and this reporter's personal obsession Rihanna, so it's not to be missed. Night all!
20.59 Wow, what a way to go. Kitty nicks the microphone from Dermot and bids farewell to her haters by belting out a few lines of 'Born This Way'. Well, she was never going to leave it at just "thank you for the experience", was she?
20.56 It's all in the judges' hands now. Louis just about convinces himself to save Kitty, while the other three all choose to keep Misha. It's happened divas, Kitty's gone. But at least we get to meet her in Digital Spy towers on Monday.
20.51 Let's see what Misha B can do with Jessie J's 'Who You Are'. Darn, it's good. I don't care if I'm sounding biased, I'm not ready to let go of Kitty yet!
20.48 Dermot correctly predicts that tonight's showdown is going to be a humdinger! Kitty's rendition of 'Over The Rainbow' is heartfelt, deep and generally wonderful. Even if she gets voted out tonight, we're glad that she finally got the cheers she's been striving for this whole time.
20.44 Also, Marks & Spencer may want to think about giving the last note of their advert to someone other than Misha. Two appearances in the bottom two is making that mooted victory a little less likely now.
20.42 Craig, Janet (cue Louis Walsh eye-shifting), Marcus, Amelia and Little Mix are through. It's a Misha B, Kitty Brucknell bottom two. Oh dear, divas, it could be judgement day. Kitty's so confident of her boot that she reels off that "I'm just happy to have been here" spiel before the sing-off has even started.
20.38 Come on then Dermot, tell us who is in the bottom two. Kitty and Janet are a safe bet, but are we on for an upset?
20.33 GaGa says that she's given Kitty a big hug backstage. I'm sure the Brucknell is made up about that. At least it will be a nice consolation for her if tonight goes the way I fear it will.
20.31 It's off with the head (ha) and on with something nice and skimpy, of course. Dermot hasn't seemed this uncomfortable since... well, the last time GaGa turned up on The X Factor. But at least he doesn't have to try and make small talk with a severed head.
20.29 Wait, hang on, she's headless. HEADLESS. Oh Kitty, we love you and all, but you have got a lot to learn from GaGa about theatricality. I'm looking forward to the awkwardness of her post-performance interview with Dermot.
20.27 Here it is. Our main event. It's Lady GaGa and she's singing 'Marry The Night'. Oh come on, a giant cross and a performance from inside a confession box - that should offend literally nobody.
20.25 And, we're back. Gary jokes that he's "not really talking" to Kelly now that she's got three acts and says that he's really enjoying time with Louis as a result. Everyone rightfully laughs at that notion.
20.20 Time for some Derm chat. Kitty's grinning from ear to ear about meeting GaGa tonight, Craig admits that he is "not confident" about his chances and Janet looks like she's already been voted out. Seriously girl, you only need to be all dark and tormented when you're singing. Give us a thumbs-up or something!
20.17 The boys seem genuinely relieved that they didn't muck up there. Also, I've only just noticed Zayn's amazing muttonchops. What is he, like, 12? How did he grow them?
20.15 Right, grab your earplugs (to drown out the screaming girls, obviously). It's One Direction. They're singing their new single 'Gotta Be You' and, more importantly, looking right on trend. Seriously, they're like a singing advert for Topman. I'm more interested in placing an order for Louis's red chinos than listening to them.
20.11 Recap of last night. We're made privy to some backstage Barlow/Tulisa bickering over his claim that Little Mix have become a bit predictable. She (rightly) points out that Craig pulls out the same shtick every week and tells him, "Have a good time with your ego." Blimey. Oh and Kelly's admitted that Janet's performance was just "alright". Doesn't bode too well for the flame-haired one.
20.08 Janet takes the lead in a group rendition of 'Walking On Sunshine', which she's clearly hating. Marcus has plumped for a front comb-over tonight for some reason and Kitty's taking advantage of what is quite possibly her last X Factor performance with some high-note showboating. Well, technically she's miming, but you know what I mean.
20.04 Dermot's on and now so are the judges. We're liking the outfits tonight, especially Kelly's black widow number. Bit disappointed by the lack of Tulisa's salute thingy though.
20.01 Kelly Rowland's 'I Got Three Girls' for Christmas No.1?
20.00 Starting nice and early today, that's what we like to see. I think lining all the finalists up in a row like that gives the impression that one is about to be blindfolded, handed a ciggie and shot firing squad-style. Now THAT would be a twist!
19.56 Evening all. As long as nobody spills Pepsi in the control room again tonight, we're just minutes away from a good old X Factor elimination. Who's it going to be? Rant away in the comments box below!
