Billie Piper worries her son will be bullied - because she played a prostitute in a TV show.

The 27-year-old actress will never let 15-month-old Winston watch racy UK TV drama 'Secret Diary of A Call Girl' - in which she plays high-class hooker Belle - but expects he will find out about it from mean children when he goes to school.

Billie - who is also famous for her role as Rose Tyler in the popular BBC sci-fi series 'Doctor Who' - said: "I'm never going to show it to my son Winston. He'll have to stick with watching old episodes of 'Doctor Who'. He's going to hear about it when he's like ten or something and someone will say, 'Have you seen this programme? Your mum was a sl*g!' I'm going to bring him up to have a very open mind, but I think he'll definitely be bullied for being my son."

The 27-year-old British star also revealed she didn't enjoy having to strip off for her role as Belle only a couple of months after giving birth.

She added in an interview with Heat magazine: "I use body doubles for certain things - just some stuff which I couldn't do for sheer embarrassment. Usually, it's just the intense grinding scenes that I can't do!"
