Britney Spears is rumoured to be filming a new reality TV show. The 'Piece of Me' singer - who filmed 'Britney and Kevin: Chaotic' with her ex-husband Kevin Federline in 2005 - has reportedly ordered her entourage to carry professional video cameras with them at all times to capture her antics on film.

A source said: "Britney's bodyguards and other staff members have been told to carry video equipment with them wherever they go so they don't miss a thing. "Whether Britney is high or low, feeling happy or sad, the cameras are there catching it all.

Some of the footage is really explosive and it's going to be must-see TV. "Britney thinks a new reality show is just the thing she needs to help her kick start her career and prove to her fans she has put her recent troubles behind her."

The singer - who received rave reviews when she appeared in two episodes of US TV sitcom 'How I Met Your Mother' earlier this year - was even videoed by her assistant while on holiday in Mexico this year, and her bodyguards have regularly been seen filming her.

Britney recently shot footage for Madonna's upcoming Sticky and Sweet Tour. The footage, which includes the pair gyrating against each other and Britney losing her mind when she gets stuck in a lift, will be screened to fans on Madonna's via 20ft screens.
