Britney Spears received death threats

Pop star Britney Spears has repotedly received death threats while on her current Circus Tour

Contactmusic.com reported that Spears has attracted the unwanted attention of a dangerous stalker.

"Britney received some anonymous death threats over the phone and in the mail, and her worst fear is a kidnap plot against (her sons) Sean or Jayden. She’s been having terrible nightmares since then and she wakes up in the middle of the night crying for her boys," said a source.
