Billie Piper's sizzling striptease in limo for 'Call Girl' film

London, Aug 21 : English actress Billie Piper has performed a sizzling striptease in the back of a limo for her new series of ITV2 drama.

Piper, who is playing the part of a hooker, could be seen shrugging off her jeans and top in an ad for the film 'The Secret Diary Of A Call Girl', reported the Sun.

The 25-year-old 'Dr. Who' star was seen stripping down to her black undies as she provocatively coats her lips with gloss in the saucy limo-scene.

Meanwhile, Piper has also revealed that she felt like a "sweaty cow" during the filming of the new series.

She further said that playing the part of high-class hooker Belle de Jour for the programme, during her pregnancy, had left her feeling anything but glamorous.

The second series of the show starts next month.
