Britney Spears plays 'super sexy 50s housewife

Britney Spears plays a "super sexy" 50s housewife in her new music video.

The 'Circus' singer dons a short blonde wig, a fitted pink top and a white skirt for the promo for her upcoming single 'If You Seek Amy'.

The pop star - who will kick off her 'Circus' tour in New Orleans next month - has spoken about the promo, which was shot earlier this week.

She wrote on her Twitter account: "The 'If You Seek Amy' shoot was super sexy and really fun! I can't wait for you all to see it. Love Britney."

It has also been revealed Britney has several costume changes and is surrounded by dancers "dressed in skimpy outfits" in the video.

A source said: "The video begins with Britney coming outside her house to hand the paparazzi an apple pie that she baked. She acts like she wants to hook up. The video is very provocative."

Britney's body is back to its former glory and insiders say she was "very professional" and "upbeat" on the set.

Another source said: "She was like the old Britney at the shoot. She was engaged and excited the whole day and seemed like her old self."

'If U Seek Amy' is the third single from Britney's latest album 'Circus'.

Meanwhile, Britney's ex-boyfriend Adnan Ghalib allegedly tried to run over a man who was trying to serve him with court papers.

Police say the victim "ended up on the hood of the car, then fell off when Ghalib drove away, and ended up with scratches and bruises".

A report for assault with a deadly weapon was taken and police are waiting to question Adnan.
