Los Angeles, Selfies are a hit among celebrities and the masses, but singer Katy Perry calls it a "disease".
The "Roar" hitmaker was enjoying her weekend at Coachella music festival here when she was asked by a fan to be a part of selfie, which has people posing for their own pictures while taking the photo themselves.
But she refused until her admirer also agreed to appear in the photograph with her, reports femalefirst.co.uk.
Perry later posted on Twitter: "Dear festival friends remember, selfing is a disease."
