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 (11.04.14) 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 (12.04.14) 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 1:30am.
"The two met up at the VIP section during Major Lazer's set and shared a friendly hug."

Mark Wahlberg joked he was given the "You're-too-f***ing-old-to-come-back award" at the MTV Movie Awards last night (13.04.14).
The 42-year-old actor had the audience at Los Angeles' Nokia theatre in fits of laughter as he gave a foul-mouthed acceptance speech when he picked up the honourary MTV Generation Award from 'Entourage' stars Adrien Grenier, Kevin Dillon and Jerry Ferrara.
He said: "I know what this really means...this is the 'You're-too-f***ing-old-to-come-back' award.
"This is not the Channing-Tatum-you're-dancing-around-chicks-want-you award. This is the you're-f***ing-done award. But look, it was a great run."
Mark - who was jailed for assault as a teenager following a string of arrests - went on to thank people he had worked with in the past and and noted he had gone from "literally being incarcerated to having a one-hit rap career to having an underwear model career."
The 'Broken City' star - who has children Ella, 10, Michael, seven, Brendan, five. and Grace, four, with model wife Rhea Durham - then jokingly confronted an audience member.
He said: "Hey, shut the f**k up, I've gotta make 'Ted 2' and get my money right."
And Mark said he felt "lucky" in both his personal and professional life, with the Entourage' movie scheduled for release next year, a role in 'Transformers: Age Of Distinction' and to be be "married to this former supermodel, Victoria's Secret model..."
He added: "I don't know how the f**k that happened."

Jodie Kidd is engaged to David Blakeley.
The British model has been on "cloud nine" since her ex-army beau popped the question four months ago following a whirlwind romance.
She gushed to Britain's HELLO! magazine: "It is absolutely brilliant. We are totally chuffed and on cloud nine."
David added: "I am feeling really excited and over the moon. I've never asked anyone else to marry me - I've never felt like this before."
The couple decided to keep their engagement a secret at first so they could revel in the happy news with their close family and friends.
Jodie, 35, added: "We just wanted to enjoy that moment for us, although we told our immediate families. I can't believe we got away with it."
David - who has served in the military for over 19 years - chose Udaipur in Rajasthan, India, as the location for his proposal after being invited to give a talk on leadership and war over there, and was nervous about Jodie foiling his plan on the flight over.
He joked: "I hid [the ring] in a pair of socks and panicked at one point when she very nearly did find it."
Jodie - who has a two-year-old son Indio, with her ex-partner Andrea Vianini - believes she has found The One in David and instantly knew he was the man she wanted to spend the rest of her life with.
She said: "It feels totally right when you meet the right person and you realise then why previous relationships didn't work. David and I are the same age and we've both been through a lot. We're older and wiser and feel very lucky to have found each other.
"I'm super happy after going through so many years op trauma and unhappiness. He is going to be a fantastic stepdad. They bonded from day one and it's lovely to see Indi have a bit of male stability."

Harrison Ford is excited about the 'Blade Runner' sequel.
The actor would jump at the chance to return as bounty hunter Rick Deckard in the follow-up to the popular 1982 sci-fi thriller and is "very anxious" to work with Sir Ridley Scott again.
He said in a Reddit 'Ask Me Anything' Q&A on Sunday (13.04.14): "I'm quite curious and excited about seeing a new script for 'Blade Runner' if in fact the opportunity would exist to do another, if it's a good script I would be very anxious to work with Ridley Scott again, he's a very talented and passionate filmmaker.
"And I think it would be very interesting to revisit the character."
Despite his enthusiasm, the 71-year-old star also admitted the most difficult set he has ever worked on was in fact 'Blade Runner' as they filmed for 50 nights in a row and "it was always raining."
It is not yet known whether Scott will ask Ford to return after the director previously revealed the Hollywood veteran was "too old" to star in the sequel.
He commented late last year: "It's not a rumour - [the sequel is] happening. With Harrison Ford? I don't know yet. Is he too old? Well, he was a Nexus-6 so we don't know how long he can live. And that's all I'm going to say at this stage."
Ford and Scott famously had a fraught on-set relationship while shooting the first movie, with the 'Stars Wars' actor branding his role as a futuristic cop "a f**king nightmare".

Baz Luhrmann could be set to direct 'Kung Fu'.
The 'Great Gatsby' director is reportedly in negotiations to take on the big screen adaptation of the 70s action-adventure western TV series, which is being produced by Legendary Pictures, according to The Hollywood Reporter.
Although it is unknown how far along discussions are, and the company are yet to comment on the project, if Luhrmann were to take on 'Kung Fu' he would be the first to rewrite the script - the current version having been penned by 'Black Swan' writer John McLaughlin - before proceeding.
The original 'Kung Fu' series starred David Carradine as Kwai Chang Caine, a Shaolin monk who travelled to the American West in search of his half brother.
The show - which aired from 1972 to 1975 and gained a cult following which continued to grow once it ceased production - also featured flashbacks to his training as a teenager in which his master referred to hip as "young grasshopper".
The current script, which could be changed by Luhrmann, is reportedly set in China, with Caine embarking on a journey to find his father, before ending up in prison where he must fight to survive.

Lorde described Coachella Valley Music and Arts Festival as "mental" when she took to the stage at the weekend.
The 17-year-old star performed at the event in Indio, California on Saturday (12.04.14) and was met with huge cheers.
She told the crowd: "This is actually the first big thing I ever booked. I said, 'Holy f**k, we booked Coachella'. I was screaming on the phone. We are so lucky to be here. This is mental."
According to Entertainment Weekly, the 'Royals' hitmaker thanked the audience for making the dreams of a "kid from New Zealand" come true.
She also took to Twitter today (14.04.14) to thank fans and wrote: "coachella week 1 all done, and we go out with blister feet and dusty hair and most importantly happy ears! goodnight freaks; we love you so (sic)."
After Lorde's performance, Pharrell Williams appeared with several guest stars, including Snoop Lion, Nelly, Busta Rhymes, Puff Daddy and Gwen Stefani.
Solange Knowles performed Kate Bush's hit 'Cloudbusting', before being joined by her sister Beyonce.
Coachella continues next weekend and artists on the bill include Arcade Fire, Beck and Calvin Harris.

Eminem and Rihanna performed 'The Monster' on live television for the first time at the MTV Movie Awards last night (13.04.14).
The pair headlined the two-hour show at the Nokia Theatre in Los Angeles, which also included performances from Ellie Goulding and Miriam Bryant, in a preview of their upcoming mini-tour which is set to travel to Los Angeles, New Jersey and Detroit this summer.
Rihanna entered the stage first, followed shortly after by Eminem and they, along with a backing band, managed to overcome technical faults to perform a crowd-pleasing rendition of their hit single for the first time on live television.
The musical pair first collaborated on 2010 single 'Love the Way You Lie' before reuniting for 'The Monster' - which Eminem, 41, released as the fourth single from his album 'The Marshall Mathers LP 2' in October last year.
Speaking previously about working with Rihanna, 26, he said that 'The Monster' was "not necessarily a sequel, as much as it is a revisitation" to his past.
He added: "To me, it's more about the vice, and it's more about the nostalgia."
Ellie Goulding took to the stage for a rendition of her single 'Beating Heart', which features on the recently released sci-fi/action film 'Divergent', while electronic DJ-producer Zedd joined her before Matthew Koma and Miriam Bryant took to the stage to play their track 'Find You.'

James Corden claims presenting the BRIT Awards was "horrid".
The comic admits having an audience that "don't listen to anything you say" was the most frustrating aspect throughout the five years he hosted the annual music ceremony, and it's something he won't miss now that he has stepped down.
Speaking during the 'Michael McIntyre Chat Show', James said: "It was horrid. It was so much fun the week leading up to it and you get to see the bands, and then it is live and you are in a room full of people that don't listen to anything you say. People who beg for a ticket and then pretend they are too cool to be there. They are chatting drinking and eating."
James, 35, admits he will miss the show following his last stint as a host in February but thinks the BRITS would benefit from having a younger host.
He added: "I enjoyed doing it and I'm sure when it comes around in February I will miss being a part of it. But it's time to hand it to someone younger and cooler."
Meanwhile, speculation as to who will take over has been rife with Radio 1 DJ, Nick Grimshaw, 29, expressing interest in the job while James has championed Emma Willis, 38.

Peaches Geldof was planning a secret Australian TV project just weeks before her death.
The 25-year-old star, who was found dead at her home in Kent, South East England, last Monday (07.04.14), was hoping to spend three months Down Under to film a new TV show, it has been revealed.
Speaking to Aga Living Magazine prior to her death, she said: "I can't say what it is yet, but I'll be there for three months. The babies will come with me because obviously I wouldn't leave them for that long."
The mum-of-two also elaborated upon her attachment parenting beliefs in one of her last interviews, explaining why she never left her children Astala, 23 months, and 11-month-old Phaedra - who she had with her husband Thomas Cohen - to cry alone.
She explained: "When babies are crying, they are too young to understand you haven't left them forever, so they are terrified."
The star's youngest son was tragically found at her side after her death and insiders hope her family will take "comfort" from the fact she didn't die alone.
A source said: "The hope is that Phaedra is so young he wasn't aware of what was going on. The most important thing is that he's OK.
"It is devastating for Tom that he wasn't there but it couldn't have been avoided."
Peaches' body has now been released by coroners so plans for her funeral can be made. Her cause of death remains unexplained.

The 'Hunger Games: Catching Fire' won big at the MTV Movie Awards last night (13.04.14).
