Britney Spears has reportedly asked old flame Justin Timberlake to join her on tour in a bid to spice up her flagging stage act.

The pop princess is hoping that her first love will take time out from romancing girlfriend Jessica Biel to help her get her mojo back.

She is also counting on the help of mother-figure Madonna, Elton John and R&B producer Pharrell Williams when she kicks off her Circus-themed tour next summer.

It's also rumoured that Britney wants to live in the UK during the four months leading up to her London shows in an attempt to get away from the US paparazzi.
