Britney Spears has been the recipient of numerous alarming letters and packages, a source close to the pop star tells E! News.
The disturbing correspondences have reportedly included one letter mentioning "how to bomb" and others full of threatening language and "weird gibberish," the Spears source said.
The threats have become so severe, that the Spears camp is reportedly going to give the mail to law enforcement.
"A lot of it was disturbing stalker kind of stuff," the source told E! News. "But to be safe her security team is turning it all over to the police and FBI."
A rep for the LAPD told E! that a specific investigation has not been launched into the disturbing mail, but they, "have been looking at allegations that have cropped up in the past couple of months."
The concerning letters and packages have reportedly been sent to multiple addresses linked to Spears.
A spokesperson for the FBI told E! the LAPD could not comment on ongoing investigations.
