The outspoken star has slammed the 'X Factor' judge after she showed off her tiny frame at auditions for the ITV talent show last week.

The former 'Celebrity Big Brother' contestant said: "I may not be a big fan of chubsters. But little Cheryl Fernandez-Versini is so tinky-tiny I feel cold when I look at her."

The 40-year-old star added in The Sun newspaper: "Cheryl, love, you need a good roast dinner and some thermals."

Cheryl, 32, shocked fans when she stepped out looking noticeably thinner than usual in a pair of tailored black trousers and matching crop top at the Manchester auditions.

However, the 'I Don't Care' singer recently spoke out against criticism of her weight after one of her Instagram followers commented that she looked like a "bag of bones".

The user wrote: "Bag of bones u looked so much healthier in the early girls aloud days with ur lovely curves (sic)."

Meanwhile, Cheryl responded: "I am so sick and tired of it being ok to call somebody too thin or a 'bag of bones'. I would never dream of calling somebody too fat and that they should maybe cut down on their food intake?

"What is the difference? You have no idea what I have been through. Just loosing my father in law v recently and everything that comes with that. Not that I am or should justify myself to anyone.

"I'm so f sick of people thinking it's ok to be mean or body shame anyone. And it's woman on woman. Have some respect and maybe think there may be reasons why before opening your mouth please (sic)."
