Tracey Emin's controversial My Bed artwork, owned by Charles Saatchi, has been sold for £2,546,500 at an auction at Christie's in London.
The Margate-born artist was in the packed auction room to see My Bed fetch a record amount for her work.
The auction house was unable to immediately reveal the buyer.
The artwork, which made the 1999 Turner Prize shortlist, went up for sale with a guide price of between £800,000 and £1.2 million.
Saatchi, who paid £150,000 for the work in 2000, sold it to support the work of the Saatchi Gallery Foundation.
