Stalker threatens to stab Britney

Pop princess Britney Spears is reportedly petrified after receiving a string of letters from an obsessive fan, who has threatened to stab her.

The man, who brags that he has Britney's name tattooed all over his body, has also been sending threats to Britney's new fiance Kevin Federline.

Kevin is now so worried that he has enlisted the protection of a bodyguard.

This is the second time the singer has attracted a potentially violent stalker. The first, Japanese businessman Masahiko Shizwaman was issued with a restraining order after a judge decided he was "abnormally obsessed" with her.

Britney and ex-model Kevin plan to tie the knot in November.
