London, Sept 4 (ANI): English actress Billie Piper, pregnant with her first child, is pleased to have a cleavage after years of complaining she was flat-chested.

Im surprisingly chilled about my body changing, I think its because I cant do anything about it. I often see myself in the mirror and laugh, the Sun quoted her as saying.

Its nice having boobs. I think when you dont have them you find ways to make yourself feel better about the lack of cleavage, she added.

The 25-year-old star, who plays the part of prostitute Belle de Jour in the second series of ITV2 drama Secret Diary Of A Call Girl, has also revealed that she had had to have body doubles brought in as her body grew bigger and bigger everyday.

Everyone had to work twice as hard as my body grew bigger almost by the day, she said.

I was shot from the waist up at first, then they had to use different body doubles as my boobs got bigger. Then just my face was in shot because my boobs were too big.

Right at the end it was my face in profile surrounded by a nest of hair because my face started to fill out as well. Everything was swelling and pulsating. I looked really vulgar! she said.

The new series of Secret Diary Of A Call Girl begins on ITV2 on September 11, at 10pm. (ANI)
