Cheeky Britain's Got Talent judge Simon Cowell was told off by David Walliams at auditions last week after he suggested like the likes of Cheryl Cole and Alesha Dixon can't sing!
The music mogul made a sly dig at the pair of popstars, saying: "Most girls who haven’t got good voices end up in girlbands.”
But Little Britain comic David was quick to stand up to Simon, defending Misteeq star Alesha: “You’re so mean to Alesha, making her sit beside me and not you.
“You always have the person you fancy next to you. We feel left out.”
It's not the first time Simon's been a bit mean towards Cheryl's singing voice however.
He previously blasted her music before inviting her to join The X Factor in 2008, saying: "That Geordie girl, she's crap. She doesn't sing a note in tune."
And Cher Lloyd has also been having a go at poor Chezza this week too, saying she'd only perform with her former mentor if she bothers to sing live for once!
