Britney Spears has requested that 45 security guards protect her at all times during her appearance on The X Factor this weekend, according to reports.
Spears, who is due to perform her new single 'Womanizer' on the reality TV show, is also understood to have banned contestants from watching her perform.
"The studio has been in lockdown since yesterday in preparation for Britney's arrival,” a source told the Mirror newspaper.
The singer is also reported to have said that she won't pose for pictures or sign autographs for anyone.
The source added: “To say it is over the top is an understatement. That not even Simon Cowell or Cheryl Cole can ask for pictures with her is beyond belief.”
As previously reported on Gigwise, the singer made her pop comeback at an awards ceremony in Germany last night (November 27th), where she also collected a prize.
