Katy Perry Katy Perry

Katy Perry isn't shy about showing off her feminine physique (just ask Sesame Street), but the pop star says she used to hate her breasts.

Watercooler: Katy Perry is far from a firework on How I Met Your Mother

"I'm generally around 130 pounds, which is totally fine for me. But when I was a kid, I was the same height and weighed more like 145. And I had enormous boobs that I didn't know what to do with, so I wore minimizers, which were not cute," Perry tells Elle. "Those thick-ass straps! I got made fun of for the over-the-shoulder boulder-holder ... and all I wanted was to look like Kate Moss. Little did I know ... that these things would come in handy someday."

The one-time Christian rocker has no qualms about her provocative style, either. "I'm a sexy girl, so what? I never claimed I was a nun!" she says.

Katy Perry video pulled from Sesame Street

Perry, who guest-starred this week on How I Met You Mother, was pulled from a episode of Seasame Street in September because the show's production company felt her music video featured too much of the singer's cleavage. The clip featured Perry in a low-cut dress singing to Elmo about playing dress-up. The singer has since lampooned the Sesame controversy during an appearance on The Simpsons and in a Saturday Night Live sketch.
