Katy Perry is talking about boys again.
But this time around, it's pretty clear she's not opening up about her split from Gym Class Heroes singer Travis McCoy.
Perry revealed at a concert in L.A. this weekend that she first started learning about the opposite sex at a roller-skating rink.
"I used to never even be able to see a boy," the Grammy nominee said to a packed house at the Wiltern. "I didn't even know what a boy was. They were so foreign to me. I used to go roller-skating just so I could see the opposite sex."
And it was there that she suffered her first heartbreak.
