Comedian Katherine Ryan has slammed X Factor's Cheryl Fernandez-Versini.
Katherine, 32, is being touted the new Joan Rivers.
The blonde star says she doesn't like commenting on how celebs look, but instead on their behaviour.
And she only flips "the b***h switch" on people who deserve it.
She hit out at Chezza saying: "My problem with Cheryl is that she doesn’t treat everyone very nicely. She’s a bit of a diva.
"She’s like ’I’m just like you’ – no you’re not, you’ve been famous since you were 15, you’re nothing like me."
Not being one to hold back, she continued with her rant bringing up some of Cheryl's controversial past: "It’s really bad what she did to that toilet attendant.
"And it is true about us that we forgave her simply because she was cheated on by Ashley Cole and she got fake teeth.”
She seems to have a lot to say about Cheryl recently, clearly just looking for press.
And the toilet attendant situation, it was one mistake 12 years ago and she has never repeated it or acted in that manner since, it was one punch when she was young, people need to move on.
