As if all that wasn't enough, Kelly's done a runner from the panel and former champ Alexandra Burke has stepped into her glittering shoes, while The Risk have nicked one of Nu Vibe following Ashley's departure. If Misha B hits out at those diva claims, we could be on for the most explosive episode ever.
Meanwhile, Louis Walsh will be providing a sense of consistency amid all the switch-ups with his usual gaffes and Kitty Brucknell's Halloween performance is surely one that can't be missed.
Share your views on the acts and follow Digital Spy's verdicts on the Top 10 performances in our live commentary throughout the evening.
21.44 So who was your favourite of the night? And what are your predictions for tomorrow? I'm betting that some combination of Frankie, Sophie, Janet (a bit drab tonight) and Kitty (unfortunately) will land in the bottom two. Let us know what you think below and join us tomorrow when Cher Lloyd and Nicole Scherzinger will be popping on stage as well. Night!
21.40 Louis thinks that Craig is a "contender" and I'll have to agree. He's been one of the most consistent contestants of the series and I wouldn't be surprised to see him McElderry his way to the end. Tulisa calls it an "amazing performance" and Alex (who's clearly been told to "be more Kelly" by the X Factor team) says he has a "beautiful voice". Both want him to "shock everyone" next week, though. Gary doesn't mind, he thinks it's the "performance of the night".
21.36 And he's doing Adele's 'Set Fire To The Rain'. Yeah, it suits him. Makes a nice change from a ballad. Ooh, they've all been a bit good this week, haven't they?
21.34 Craig Colton's closing the show and he's even achieved radio play in his native Liverpool. On a side note, what's the braces epidemic sweeping Merseyside?
21.33 Little Mix are definitely on course to beat the girlband curse. One of the best performances of the night, I reckon. Alex thinks they have "potential" and Louis takes the opportunity to unleash his "out of this world" pun. Very good, Louis. Oh and apparently that girl's called Jessie. Digital Spy loves you really, Jessie.
21.29 Ah, me likely the possessed doll in demonic playground thing going on there. And 'E.T.' is a good fit for them. Good work, Tulisa!
21.27 Let the spookiness recommence. It's Little Mix and they've had a bad week, being pressured into changing their name and whatnot. We really hope that Digital Spy was not one of those websites that reduced whatsherface to tears. If so, apologies #4 or whatever your real name is.
21.19 A great performance of 'Sweet Dreams' by Kitty. Tulisa says that she's the "most inventive" act, but Alexandra says she might come across as "slightly cabaret". As much as I love Kitty, there is a fear creeping in that she'll soon be overshadowed by her magic tricks. Also "that's burlesque, darling" has got to be a contender for the gayest comeback ever uttered.
21.15 We're asking WTF already and Kitty hasn't even sung a note. Spinning on a sparking Catherine wheel - that's our girl. Shame about the botched dye job.
21.12 Oh yes! It's Kitty and it's Halloween. Match made in mental heaven? Right guys, please don't let her get in the bottom two again this week. I'll break your faces.
21.10 Tulisa's a fan of the "rebellious" and "wild" Frankie, but Alex is "confused" as to how seriously he's taking the competition. Frankie, somewhat bewilderingly, tells X Factor winner Alexandra that she wouldn't understand how press rumours jar with life in the house. Anyway, Frankie might still be here next week. I'll admit that he's done worse.
21.06 Blimey, and I thought last week's backstage bit was cheesy and contrived, but sticking Frankie in the middle of some rented screaming fans is just....urgh. For all of Gary's comments about Louis turning Johnny into a joke act, we're getting serious Wagner vibes from Frankie right now. And he's really asking for trouble singing 'Should I Stay Or Should I Go'.
21.03 Take your spots in the comments section, it's Frankie Cocozza. He says he's been "naughty" again (well, his future in the competition depends on it) and states that he is no "cheesy, choir boy singer". Agreed Frankie, you are none of those things.
21.01 Louis says that her rendition of 'I'll be watching you' was "haunting" - well, it is Halloween, mate (also PLEASE stop doing Kelly impressions). Tulisa says that Janet must "mean business" and is a "contender". Gary notes that she is "predictable in a good way" but worries that maybe viewers will forget her. Could Janet be the obligatory mid-series shock exit?
20.57 Oh hello, very macabre. Janet suits the haunted house look but I think it's about time she blew them cobwebs away with something that has a bit of a kick.
20.55 Well, now that the Misha B fire has been thoroughly doused, we need another controversy. Maybe Janet Devlin is gonna smack Louis out mid-performance. Probably not, but let's see.
20.50 Louis kisses Kelly's bum by paying homage to her "put it down" bit. Tulisa says that Misha "smashed it", "was born a star" and she basically does some class-A wiggling out of last week's awkward situation. Gary, meanwhile, says that Misha is "out of the stratosphere" and Alex urges her to continue climbing the fame ladder. Ah, see, everyone's all happy again...how boring.
20.46 Another week, another strong performance - this time it's 'Tainted Love', but all rappy and the like. With that hoodie-come-loo roll cover outfit and her hair horn she's even starting to out-weird Kitty.
20.44 It's Misha B time. She addresses "bully-gate" and says she had to "pinch [her]self" to check if she was really accused of being abusive on live TV. She says "sorry" to anyone she's hurt and claims that she was "saved by music". Frankly, we just want to fast forward through the performance to see what Tulisa and Louis say this week.
20.39 Good reviews for Marcus's "fun" take on 'Very Superstitious'. Alex is channelling Kelly Rowland's bizarre buzzwords scarily well. What does "you snatched it" mean?
20.36 Yeah, I'll take that. The crippled G.A.Y. friendly Riddler look is alright. And he looks very comfortable with a stick in his hands (sorry, but come on). Marcus is starting to look like a proper artist and he is a natural showman - he could go far.
20.33 It's Marcus time. He's a fan of the eccentric so hopefully we'll get something big and bold from him for Halloween. Just as long as it's better than 'Moves Like Jagger'. That was dire...it was, you know it.
20.31 Joking aside, that bit of 'Bang Bang' and the spider-mistress-chic she sported was pretty good. Oh, well the panel don't agree. We never do. Louis likens her to "a secretary who sings at the weekend" and Gary labels her "dull as dishwater". I kind of liked it, though.
20.29 Well if you want to grab attention, I guess sitting in a chair made of half naked men is a good way to start. What I want to know is how are the X Factor team going to carry that back to its rightful place in the Digital Spy offices?
20.27 Sophie's gone back home and explored her Lahndahn roots in an attempt to appear interesting. Keep going Soph, you'll crack it eventually.
20.26 And we're back! Who's next? Alexandra's taken charge of Kelly's girls like some strange singing cuckoo and the first one she's wheeling out is Sophie Habibis.
20.22 We're not sure we agree with Tulisa's assessment of Johnny being "sexy" (though Gary clearly couldn't contain his love any longer and leapt on stage), but yeah, he was brilliant. Alex says he is "very special" and Gary's glad that Johnny is finally getting songs suited for him. The only downside is Louis is going to be smug all night long now.
20.18 Aah, brill. Louis has finally decided to de-Wagner Johnny and give him a REAL SONG. It's Ella Fitzgerald's 'That Old Devil Called Love'. And it is PERFECT for him. Brilliant.
20.17 Next it's crazy ol' Johnny Robinson. I love how's he's referring to Mr Barlow as "my Gary" - Best. Showmance. Ever. Aaw, and it is sweet how he's getting bombarded with autographs and free cocktails right now. I'm even prepared to forgive him for beating me to the 'Here's Johnny' Shining reference.
20.14 Louis loves it, Alex says they have "a little summ'n summ'n" (is this the new "put it down"?) and Gary Barlow even likens their situation to Robbie's Take That exit. Yeah, everyone likes it, but I do think the reaction is more to do with their situation and not the performance.
20.11 Michael Jackson's 'Thriller'...on Halloween night. Ok, fine, we'll let Tulisa off for that painfully obvious song choice given the circumstances. Hmm, you can tell they've only just got together. It's all a bit...meh. It's not very polished, a bit safe. But like I said that sob story will do the business.
20.09 Oh come on X Factor, you are not playing fair dropping The Risk in the death slot just 24 hours after they got together. Mind you that sob story VT they pegged on - 'Jar Of Hearts' and all - could probably get them enough sympathy votes to make it through already.
20.07 Wow, check out those Dermot moves. Get away random backing dancers, we want the judges! Tulisa's gone all Catwoman and Alexandra is dressed up like a Christmas cracker for her big moment. Oh, and funny how they go to Tulisa for the whole "sending Kelly love" shtick.
20.04 Unintentional laughs aplenty in that VT with Louis describing Halloween as the perfect theme for Kitty and Johnny and Gary lamenting the lack of 'love' going on in his dressing room. Ooh er.
20.02 Showtime. Oh good, they decided to underplay all the chaos of the week. Classy...nah, they've got Louis Walsh jibbering like a crazy person over Kelly Rowland's absence.
20.00 Are you looking forward to Halloween week? It was an absolute belter last year thanks to Cher Lloyd's 'Stay' and the sight of Tesco Mary in lil devil horns. I can't wait to see what this lot have come as.
19.58 Hello everyone. It's a Saturday night and you know what that means. It's time to face the music because The X Factor is here. Well, it's been quite a week over at X Factor towers with the boyband swapping, Misha madness and the last minute introduction of Alexandra. We wonder how all that madness will effect tonight's performances.
