Kerry Katona is auctioning her old breast implant to raise money for charity.

The MTV star revealed on her Facebook page that she is selling the lump of silicon on auction site eBay.

She wrote: "I have put my old implant which was removed on my MTV show watched by the nation up for auction on eBay! The money raised will be donated to the Breast Cancer Campaign.”

Bidding- which lasts until March 20- currently stands at £360. Katona and hubby Mark have said they will donate £500 to the charity as well.

The implant is signed ‘lots of love Kerry Katona’ and features a self portrait of the former Atomic Kitten star.
