London, Mar 9 : Troubled singer Britney Spears is being stalked through strange letters, and has been receiving threatening notes and packages, according to reports.
The 26-year-old star is being bombarded with strange letters and DIY (Do It Yourself) Bombmaking instructions.
Sources say that the singer has called the FBI for help.
"She's received disturbing, stalker stuff. The security team has turned it over to the FBI," News Of The World quoted a source, as saying.
Meanwhile, Spears' ex-beau Justin Timberlake has come to the fore and is comforting the "Toxic" star on the phone.
The 'SexyBack' singer was allegedly quite distressed over Britney's troubles and has thus decided to lend his support.
"JT just wants to see the girl he once fell for well again," said a source.
