The founder of Britney Spears’ biggest web-based fan club has decided to shut up shop.

Ruben Gray insists: ‘Britney is losing her identity and credibility. Britney is done. For me at least.

‘No matter what anyone thinks or how they may disagree, it is very hard to maintain the respect needed to keep things going.’

Ruben and his members have been disappointed to see mum-of-two Britney, 25, out partying with Paris Hilton since filing for divorce from Kevin Federline.

The singer has also been photographed on four occasions without underwear,

www.worldofbritney.com has had almost 37 million visitors since it opened in 2000 but will officially close on 31 January.

Still being spotted out on the town, Britney is said to want to adopt a tsunami orphan, a four-year-old boy called Wang, from Bali, who lost his entire family in the 2004 tragedy.

A source says: "She is sponsoring him until she can find out more. She is even in talks with Madonna about it and is taking it very seriously.’
