Los Angeles, Jan 31 (IANS): Actress Katherine Heigl used to pray and fast to get a more curvaceous upper body.

She desired it because she was "super flat-chested" during her early teenage years, reports femalefirst.co.uk.

Speaking on talk show "Conan", the 36-year-old actress said: "I was a real doormat in those years and I was a very late bloomer so, by like 14 and 15 I was super-flat chested and the boys made a lot of fun of me.

"My favourite was, 'Hey Katie, would you wear shoes if you didn't have feet?' to which you reply, 'No, of course not...' and they reply, 'Then why are you wearing a bra?' It was pretty terrible. I spent the next however many months and years praying and praying and praying to get big b**bs, like that's all I wanted.

"I prayed. I fasted for big b**bs. I grew up Mormon and once a month you have a fast and testimony meeting and you're supposed to skip two meals and fast for things that matter. Good health. Safety of the family. World peace. That sort of thing. I fasted for big b**bs."

However, Heigl admits that the larger size has it's own set of problems.

"The problem is, no one warns you that... with real larger size breasts come issues... like, gravity and bigger butts and bigger thighs. So I've had to spend the rest of my life with big b**bs trying to make sure everything stays tight and where it is supposed to," she said.

When asked if she thinks that's god's revenge, she replied: "I do. Right, he's like, 'You're that shallow, try this'."
