Playing the role Belle de Jour in the hit U.K. TV show, Billie Piper found out that it was difficult to lose weight in just a couple of weeks after giving birth to her son.
British actress Billie Piper regretted signing up to star in a third series of "Secret Diary of a Call Girl" - because she had to shed her baby weight in just six weeks. The former singer - who portrays real-life escort girl Belle de Jour in the hit TV show - gave birth to son Winston in October, 2008, her first child with husband Laurence Fox.
But just weeks later Piper was due back on the set of the hit show - so she was forced to give up all her favorite sweet treats in a bid to regain her pre-pregnancy figure.
She says, "I was contractually obliged to do a third series and I had to get in shape quite quickly. After you have a kid... it feels like your only treat is eating. You can't go out or dance your a**e off, so you stay at home and stuff yourself with cake."
