The former finalist and last year's co-host is back and focusing on the music this time around with a performance of his new song.
Although he still reckons his presenting with Caroline Flack wasn't THAT bad.
"I feel that we got the hard end of the brush really. I don’t think we did a terrible job. We all make mistakes," Olly said recently.
He added: "There’s no hard feelings, but I’m so happy to be back to my music."
Olly insisted that despite the axe, his relationship with Simon Cowell and the show was "still amazing".
"That’s why I’ll be back [...] to perform music,” he said.
As well as Olly, former The Wanted singer Nathan Sykes will also be performing on the show during Sunday's latest live episode.
Last weekend saw the fifth X Factor 2016 results of the series as Four Of Diamonds bowed out of the competition.
They were eliminated in the sing off against Saara Aalto, while Sam Lavery was saved from the bottom three thanks to the new 'life line' vote twist.
After the latest gut-wrenching elimination, host Dermot O’Leary was joined on stage by the remaining seven contestants to decide the next theme with a spin of the jukebox.
Oscars, 80’s, and Louis Loves (the Louis Walsh collection) were still available but it was Disco week the jukebox decided on.
"I'm ready to smash this one up to pieces," declared Honey G.
The top seven act will each take on a brand new song this Saturday night as the competition heats up.
The X Factor 2016 airs Saturday and Sunday night on ITV at 8PM.
