Gary Barlow has joked that his friendship with Robbie Williams is over after the 'Candy' man voiced his support for X Factor's Rylan Clark.

Clark and judge Barlow have had something of a frosty relationship on the series this year, with the Take That man at one point walking off stage after the flamboyant singer was kept in the show ahead of his own act.

Barlow's bandmate Robbie Williams has now stirred things up even more by tweeting his apparent support for Clark, saying:

"TEAM RYLAN ALL THE WAY. VOTE RYLAN."

The X Factor judge has responded to the tweet, joking that their partnership is no more. He said:

"It was going so well between the two of us, 20 years knowing each other. We did an album together and it's all over in one tweet. In five letters it's all over!"
