The star's management took the decision after experts said chart music quality will continue on a downward trajectory relaltive to Spears, before bottoming out in 2569.

A spokesman said: "To many 563 years may seem like a very short space of time, but she's really not that bad."

Musicologist Dr Julian Cook explained: "By 2569 popular music will have degenerated to the extent that the Academy of St Martin in the Fields will take down its portrait of Schubert to make way for a poster of Dappy from N-Dubz.

"The biggest-selling track will be a recording of dead mammals being dropped by a ginger child into a huge steel container, probably entitled Bonk or Beach Tits."

He added: "Meanwhile the educated cultural elite will flock to elegant concert halls to hear renditions of Sisquo's Thong Song performed by a collective of muscular dwarves in bondage gear.

"TV talent shows will also continue to be a prime source of musical degradation, particularly Britain's Got The Ability To Press The Demo Button On A Keyboard and The Vaginal Flute Factor. Thus I predict moderate success for a defrosted Britney, if she can stay off the sauce."

However, those close to Britney are concerned about similar plans by the singer's ex-husband, who has named himself 'K-Fed' after an obscure budget supermarket chain.

An insider said: "Britney is terrified that K-Fed will emerge from a deep freeze in 600 years time clutching a now-archaic sex tape.

"However experts have reassured her that by then pornography will be so ubiquitous that slobbery blowjobs will be a type of formal greeting considered obligatory even in high-level business meetings."
