As a follow-up to her hilariously crazy music video ‘Birthday,’ Katy Perry is releasing “unseen footage” from the production featuring each of her five disorderly characters. Watch the behind-the-scenes video here!

There have been so many lip syncing videos coming out.  Dads and daughters, best friends, and now, the Rosenberg Police.

Katy Perry has done it all — she’s released platinum albums, toured all over the world, debuted a big-screen movie and signature fragrance. Now, the pop star is taking on another side of the music biz with Metamorphosis Music, a joint venture record label with Capital Records.

In July, Katy Perry will have the honor of being Cosmopolitan's first global cover girl. Perry will grace the covers of Cosmo around the world, including Australia, Singapore, Vietnam, Germany, UK and more. Perry is interviewed by talk show host and comedian Chelsea Handler for the magazine, and Perry opens up about her exes, dating and her sex life.

John Mayer was asked by TMZ on the idea that his ex Katy Perry will be writing songs about him. "You're supposed to write songs. You're just not supposed to tell everyone you're doing it."

As if Katy Perry's sultry V magazine spread with Madonna wasn't enough, she just had to go ahead and pose for a shot with yet another pop icon: Adele! Be still our hearts.

Neither Katy Perry or Madonna are strangers to getting a little provocative, but when the two pop divas came together for a cover spread in V Magazine's upcoming issue, the two were more deliciously scandalous than ever.

Though both Lady Gaga and Katy Perry have repeatedly insisted that they are not competing against each other, it looks like Mother Monster may have had a change of heart.

We love the fierce determination at the root of Katy Perry's 2013 hit, 'Roar,' but the song tugged at our heartstrings in an entirely different way when covered by a five-year-old cancer patient.

This might be the sweetest video we have seen all week! 5-year-old Kai Langer, aka the most adorable little kid on the planet, stopped by the 'Ellen DeGeneres Show' to chat with the host and show off his rendition of Katy Perry's anthem, 'Roar.'

Has Katy Perry moved on to another man already?

Katy Perry is no stranger to adopting hysterical personas for her music videos (remember Kathy Beth Terry from 'Last Friday Night'?), but she has gone all out in the vid for her latest single, 'Birthday.' While the lyric video was sugary sweet, this video is anything but, featuring Perry as five different party personalities all pranking a wide range of birthday parties.
