POLL: Who sang best on The X Factor semi-final?
NOW that all four acts have sung for a place in The X Factor final, who won the night for you?
Who will go through to the X Factor final?
Only three can perform in Wembley next week for a shot at Ben Haenow's crown, with one act set to go straight home.
Lauren Murray, Louisa Johnson, Che Chesterman and Reggie'n'Bollie sang two songs each tonight, with only Louisa winning unanimously strong feedback from the judges on both occasions.
After Lauren sang Beyonce and Naughty Boy's Runnin' (Lose It All), Simon Cowell called her "exhausting" but added: "Actually, you've just proven you are a fighter. You didn't have a great first song, you come out with a second song… I think Naughty Boy may have just helped you there. That was a great performance."
Nick Grimshaw added: "You talked about finding yourself and that's why that song worked for you. You're so comfortable to watch because you're 100% relatable."
Reggie'N'Bollie could go to the final
Che Chesterman left Nick and Cheryl Fernandez-Versini in tears with his performance of Amy Winehouse's Love Is A Losing Game, with Cheryl saying: "I think Amy would have loved that. Fantastic."
Simon, however, said: "I don't think it was a very good version if I'm being honest. Number one, I thought the production was like a karaoke track. It wasn't cool. I thought you were sitting above the track, you weren't immersed in it.
"It was good but it was a bit ordinary."
Louisa had all four judges on their feet after singing the Christina Aguilera version of It's A Man's Man's Man's World, with Simon Cowell "praying" that viewers didn't assume he was safe.
Lauren got a mixed reception
Che Chesterman gave emotional performances
On Reggie'N'Bollie, Simon said of their first song: "Your worst performance so far. I think you're very lucky you've got a second song."
Their second rendition, a mash-up of I Gotta Feeling and I Like To Move It, prompted mentor Cheryl to say she'd saved "the best for last".
But who will make it through?
The X Factor continues Sunday at 8pm on ITV.
Will Louisa go through?
