Katy Perry's 'Almost' NIPPLE SLIP !!!

KATY PERRY loves a controversy, so what better way to stir up a fresh one than by having a wardrobe malfunction on stage (?)

The singer, 24, was performing new single Hot 'n' Cold during a charity gig in Canada when her top suddenly gave way.

Despite her tender years, she acted like an old pro - covering herself up and acting like nothing had happened.

At least she'll be known for doing something else apart from singing that I Kissed A Girl song.

im pretty sure u can see the nipple in the bottom picture

Yeah you can see!
