American socialite Kim Kardashian used to cry over her breasts during puberty.

Kardashian used to hate her body and wondered why it developed early unlike her schoolmates. She felt uncomfortable with her changing physique.

"I was the first girl in my class to wear a bra. I remember crying in the bathtub. All my friends were super-skinny," the reality TV star said.

She also said that she even tried a ritual to stop her breasts from growing.

"I took a washcloth, made it hot, put it over my chest and prayed, 'Please don't let them grow any bigger. They're embarrassing me.'"

Kardashian is thankful for having spoken with her mother Kris Jenner.

"She helped me with my outlook: I have curves and that's never going to change, so I'd better start embracing them," she told Shape Magazine.

After encouragement from Jenner, Kardashian decided to pose for the December 2007 issue of Playboy.

"I'm sorry I did Playboy. I was uncomfortable," she said.

"'Go for it,' my mother said, 'They might never ask you again. Our show isn't on the air yet. No one knows who you are. Do it and you'll have these beautiful pictures to look at when you're my age.' "
