Watch out David Walliams - Simon Cowell has a new bromance.

Cheryl Fernandez-Versini has issued a warning to Britain's Got Talent judge Walliams after she spotted Cowell getting friendly with new X Factor panellist Nick Grimshaw.


"Nick and Simon are the new David and Simon," she told the Daily Star. "They are like two big kids. I think David Walliams needs to watch out because Simon has a new boyfriend."

If Cheryl sounds like she's stirring the pot, maybe it's because Nick and Simon have mainly bonded over taking the mickey out of her.


"Me and Simon love each other," Nick said.

"David is out and I'm in. I think we upped it to a new level this week, because we wound Cheryl up something rotten. I love her but she is so easy to wind up and she can't help but react. We were both making cat noises at about 11.30pm and driving her insane."

Boys will be boys...

The X Factor will return to ITV later this year.
