Los Angeles - Katy Perry thinks selfies are a disease.
The Roar hitmaker was enjoying her weekend at Coachella music festival in California when she was asked by a fan to take part in the
recent craze - which has people posing for their own pictures while taking the photo themselves - but refused until her admirer also agreed to appear in the photograph with her.
The star later wrote on Twitter: "Dear festival friends remember, selfing is a disease. (sic)"
Katy was joined by stylist Johnny Wujek at Harper Bazaar's private Shop Bazaar pool party at The Parker Palm Springs on Friday and though she was looking forward to taking in some music, she planned to just "go with the flow" as she didn't have anything definite lined up for the weekend.
She told Pret-a-Reporter: "I'm just going with the flow. I don't have a schedule."
On Saturday Katy - who recently split from John Mayer - was seen hanging out with Twilight
hunk Robert Pattinson at the H&M Loves Music party.
A source told Celebuzz: "They arrived separately 10 minutes apart from one another around 01:30.
"The two met up at the VIP section during Major Lazer's set and shared a friendly hug."
