The Pussycat Dolls are working on a behind-the-scenes documentary about life on their tour.

The raunchy dance troupe has reportedly started filming a project, which has been described as part documentary and part entertainment.

“The girls have been offered lots of film scripts in the past but they have turned down offers as nothing has been right,” a Metro source said Wednesday.

“This is something they felt was a good idea. It will show an insight into what life is like on the road and what really goes on behind the scenes – the highs and lows.”
