Cheryl Fernandez-Versini reckons her X Factor boss Simon Cowell looks like a potato.

The singer and panellist on the ITV contest - who famously fell out with Simon when he axed her from the US version of the show - made her comment during an online interview during which she was asked to do a simple sketch of the music mogul.

Showing off her version of Simon with a thick tuft of hair on what looked like a spud, Cheryl said : "A Mr Potato Head - do you remember you used to water the potato until the hair grew? That's what he looks like."

Little over a week ago, Simon was taunting her on-screen by calling her Kermit because she was wearing a green dress during The X Factor.

As she drew her sketch for the Mirror website, Cheryl said: "There's many things I want to draw but I won't. I will remain professional."
