Britney Addited to Marathon Sex

Dr Lillian Glass, a top Hollywood psychologist, has claimed that Britney Spears has become an unhealthy sex addict.

The 'Slave' singer's friends have reportedly revealed that she spends long hours beneath the sheets with her fianci Kevin Federline.

But Glass has reportedly warned Britney that too much of sex is bad news for her health and 'pop star looks'.

"She's so consumed with sex she's neglecting herself. She looks terrible and this is not a good thing for her own well being as well as her career. Too much sex can be hazardous to your health," Rate the music quoted Glass as saying.

"Britney says sex with Kevin is ten times better than with her ex-lover Justin Timberlake. They're constantly in bed together in one long sex marathon," said a close friend of Britney.
