It's finally time for the first live show of The X Factor 2017 and the Boys and Girls are up first.
This year will see contestants' performances split between the Saturday and Sunday nights.
For the first weekend, the Boys and Girls will perform on Saturday while the Overs and Groups will sing on Sunday.
Tonight's opening theme is 'Express Yourself' as each act gets the chance to show exactly what they represent and who they are as a performer.
Current favourite Grace will be singing a brand new original song, saying of her performance: "I've heard there's a few letters on stage spelling out my song title, I might be sat on top of one.
"I'm more excited about the red microphone I'm apparently having! It's an original song called Too Young and it's about making silly mistakes when you're younger. It's a big power song for me."
Meanwhile, Rai-Elle said of her mega mash up: "You're going to see some rapping and some singing, a lot of dancing. It's a medley."
As for the Boys, Spencer Sutherland said from rehearsals this evening: "I'm feeling pretty excited, a little bit nervous.
"I'm singing Who You Are By Jessie J It's going to be so much fun... let's do it!
The X Factor 2017 airs LIVE on ITV this evening (Saturday) from 8:20PM with the first performances.
The show then continues on Sunday night at the earlier time of 7PM.
