Britney Spears is collaborating with the Pet Shop Boys on her new album. The 25-year-old singer is determined to return to the charts with an edgy new sound and wants British electro pop duo Chris Lowe and Neil Tennant to help.

A source said: "She heard the remixes they did for Madonna and was blown away. She hopes they can weave some of their magic on her tracks too."

Britney has vowed to concentrate on her pop comeback, after spending the past few months partying following her split from husband Kevin Federline. An insider at her record company said: "It's virtually all done and it's not weepy stuff but uplifting pop. She's determined to be the No 1 female pop star again."

The Pet Shop Boys are known producing songs for established stars. They recently worked with British singer Robbie Williams on upcoming single She's Madonna.
