Kerry grabbing a Subway earlier this month It's not often you hear celebs say they want to pack on pounds.

But Kerry Katona claims that after dropping a whopping six stone she's taken things too far.

The former Atomic Kitten unveiled a spanking new bod to the world recently, following a boob reduction, lipo and hardcore fitness regime, but now says she is underweight.

Kez told OK! magazine: "I'm eight stone now but I want to be eight and a half. I'll be happy then because I don't like being this thin."

Blimey, some folk are never satisfied.

Kerry also revealed that she now weighs less than when she was in the band in 2001.

Kerry reached 14 stone when she was pregnant but claims the pounds dropped off with her prescribed medication: "My new medication can make you either put on weight or lose it and it's making me lose it.

"It's brilliant, but Mark says they make me a bit nasty."

Erm, maybe not so brill then?

She's also sticking to a very sensible diet: "I have bran flakes for breakfast, then chicken breast and salad for lunch and usually the same for dinner."

You might want to chuck a few choccie bars in there if you want to top-up half a stone Kez.
