Katy Perry suffers from OCD

The ‘I Kissed A Girl’ hit-maker admits she has the condition,which can cause sufferers to become upset when their routine is disturbed,Q magazine reported.

Perry’s OCD is at its worst when she is on tour and even a small problem like cat hairs on her clothes can cause her to throw a tantrum. “I certainly have an OCD side when I’m on tour… What are my areas of OCD? Well,if there’s broken make-up in my purse I freak out. Also if I am around household pets and some of their fur comes off on my cardigan,then I can get pretty sharp,” she told the magazine.

“But my worst one is if I see a pair of sunglasses with fingerprints on them. Truly,I cannot stand it. I go ape. ‘Oh my God,I can’t breathe! Wipe them clean! Agghhh!’,” she added.
