Britney Spears is set to show her recent troubles haven't robbed her of her sense of humour in new documentary Britney: For The Record.

The former troubled star is caught on camera imitating her father Jamie while on the set of her Womanizer video.

Britney - who is dressed in her sexy secretary outfit - paces back and forth while shouting down a phone for comedic effect.

The pop princess recently told MTV News, "I wanted to make this film because I started to feel like I wasn't being seen in the light that I wanted to be seen in."

We hope this isn't a sign that her ropey British accent is making a comeback...
