Former X Factor contestant Paul Akister made an appearance on last night’s show as he attempted once again to prove he has the X Factor.

Louis sent the wannabe star home from the judges house last year, feeling he lacked confidence when performing and wasn't ready for the big time.

But after a rendition of John Lennon’s Jealous Guy on last night's show, Simon told Louis: “I think Louis, you probably owe him an apology.”

As was to be expected, Simon and Louis fell back into their familiar pattern of bickering, as Simon goaded the Irish judge into admitting he made a mistake by sending Paul home last year.

After some petty back-and-forth, during which Louis stood his ground and claimed he made the right decision, Simon said: “It’s a shame I wasn’t here last year, but I’m here now.”

So Simon thinks he can save the ailing talent show? Are we all just going to forget US X Factor…?

Paul received four yeses from the panel after his emotional rendition, with Mel B calling his performance "sexy" and Cheryl saying he was "an incredible singer" – do you think they made the right call?
