Dermot O'Leary is leaving "The X-Factor" UK after serving as a host since season four.
"I'd like to wish the team all the best for the future, especially whoever takes over from me," he said.
"After eight wonderful years on @TheXFactor it's time for me to move on. I'd like to thank ITV, Simon, The X Factor family and particularly the viewers, all of whom have been a big part of my life for so long," O'Leary tweeted.
A rep for "The X-Factor" said, "We'd like to thank Dermot for eight brilliant years at the helm of The X Factor. He has been a fantastic host, masterfully keeping the show on the road, supporting the contestants throughout the competition and keeping the judges in check. We will miss him and his dance moves and wish him all the best for the future."
O'Leary's departure fuels rumour that he is eyed to replace "Top Gear" host Jeremy Clarkson who was fired by BBC after a "fracas" with a producer.
There are no words on who will replace O'Leary on "The X-Factor".
The show's rep said, "An announcement on the host for the new (season) will be made in due course.
