Is Britney Spears being stalked -- you know, by someone other than the paparazzi?
According to E! News, the Britster has been receiving a bunch of curious letters and packages, with one letter mentioning "how to bomb" and others full of threats and "weird gibberish."
Britney's peeps and her pop are worried enough about the sender that they plan on having the authorities look into the situation. "A lot of it was disturbing stalker kind of stuff," said an insider. "But to be safe her security team is turning it all over to the police and FBI."
Has anyone seen Sam Lufti lately? Just askin'.
