Kelly Osbourne's mum Sharon had a gastric band fitted in 1999

Kelly Osbourne has strongly denied claims she's planning to have a gastric band operation.

A tabloid has claimed the rock chick wants to follow in her mum Sharon Osbourne's footsteps by getting surgery to stay slim.

'Kel's at her wit's end over her weight,' a source told the Daily Star Sunday.

'She knows a gastric band would be drastic but she's desperate to keep the weight off.'

But Kelly, who models for Madonna's fashion line Material Girl, says the claims are totally false.

'The story is mental & completely untrue,' she Tweets. 'Ever heard of fact checking first? I DO NOT WANT A GASTRIC BAND!

'Where the hell do they come up with this bullsh*t? its so hurtful!
