Fans, next time you see Katy Perry, you might want to think twice about taking out your cellphone and trying to grab a selfie with the pop superstar.

Warning: You will want to nom all of the incredible-looking confections in Katy Perry's lyric video for her song 'Birthday.' Just letting you know in advance.

Katy Perry didn't attend the 2014 Kids' Choice Awards this year, but she did hint that she planned to dye her hair slime green, which is the show's signature prank and color. She wasn’t kidding. The singer has gone green, and the hair hue is perfect for spring.

Ladies always go for the bad boys after a major break up! Is this true for Katy Perry? Is she dating Riff Raff? He says they are, and TMZ has the proof!

In an interview with Australian radio station SAFM, Katy Perry was asked the inevitable question about her "competition" with Lady Gaga for pop chart dominance, since the two singers, while markedly different in style and sound, dropped singles and albums around the same time last year.

Katy Perry really is a do-gooder! The singer must be trying to earn sainthood, since she reportedly gifted her team of assistants with electric cars.

When Lorde called in to Australia's 'Kyle & Jackie O. Show' last week, she did more than just craft the perfect retort to the hosts' implication that she was in a lesbian relationship with Taylor Swift. The 'Royals' phenomenon also revealed why she turned down the opportunity to open for Katy Perry on the 'Dark Horse' singer's upcoming tour.

Well, that didn't take long! Shortly after Miley Cyrus lashed out at Katy Perry and John Mayer, the 'Dark Horse' singer responded!

Ouch! After Katy Perry went on an Aussie TV show to say that she pulled away from Miley Cyrus when the singer tried to slip her the tongue in their kiss-seen-round-the-world because "God knows where that tongue has been," Miley has retaliated, rather meanly, on Twitter.

If Katy Perry's singing career flops, perhaps she has a future in weather forecasting. While on the set for a news interview, the American singer took to the weather forecast and nailed it!!!

Katy Perry was candid and vocal about a lot of things while Down Under and appearing on 'Sunrise,' a breakfast TV show in Australia.

Katy Perry is roaring back to the stage in her Prismatic World Tour this year and we want you to go!

Katy Perry, midwife?

On, off, on, on, off. Up, down, up down. Katy Perry and John Mayer's romance sure is a roller coaster. Months after reports that an engagement was inevitable and weeks after Perry was seen wearing a rock on that finger, the musical duo is said to have split… again.

She kissed a girl and she liked it! Katy Perry reportedly enjoyed the kiss that Miley Cyrus planted on her during the 'Wrecking Ball' singer's L.A. Bangerz Tour stop on Feb. 22.

In her March Vogue cover, Rihanna admitted to wearing gobs of cheap jewelry, specifically from mall retailer Claire's, saying, "My jewelry’s all fake—from Claire’s." Well, it looks like RiRi will continue to wear pieces from the teenybopper store, as her bestie Katy Perry is now designing and creating a line of jewelry for Claire's.

She famously sang "I kissed a girl, and I liked it," but that wasn't the case at all when Katy Perry straight up denied Miley Cyrus a make-out session on the Bangerz Tour stop in L.A.

Katy Perry and Rita Ora are two of the most stylish pop stars of their generation and they each do so much more than sing. They showed off their catwalk talents by making cameos on the Moschino Runway in Milan on Feb. 20.

Katy Perry is a queen of many wigs in her 'Dark Horse' video, which has an Egyptian them, look, vibe and feel. Perry even channels Cleopatra aka Katy-Patra with her makeup and attire, but she is modernized with a grill.

Katy Perry brought out her new Katy-Patra alter ego at the 2014 BRIT Awards tonight (Feb. 19), rocking a blunt bob and bangs with a crew of neon-haired dancers on either side.
