X Factor's Dermot O'Leary is leaving the show after eight years as its host.
In a statement he said it was time to move on and thanked Simon Cowell and the viewers of the programme.
He said: "I'd like to wish the team all the best for the future, especially whoever takes over from me."
So who did you think should replace Dermot?
I think Mark from Sam and Mark should replace Dermot.
I think Olly Murs should take Dermot's place.
I think Olly Murs or PSY.
I think that Ben should host now because he won it so he'd know what to do and what to say.
Millicent, West Yorkshire
I think James Corden should replace him.
I think the new X factor presenter should be Holly Willoughby.
Harry, West Yorkshire
Maybe Pixie Lott or Selena Gomez.
I think that Jessie J should be the new presenter on the X Factor.
I think Louis Walsh should take over because he is a perfect fit for the job.
I think that Zayn Malik needs a job now because he left One Direction.
I think it should be Demi Lovato because she is an amazing singer and it should be someone else this year.
Adele, St Helens
I think Alexandra Burke should replace Dermot because she knows the pressure
I think Rita Ora should replace Dermot.
I think that Barney Harwood should take his place because he's good on Blue Peter. I love his jokes.
