Revealing she got sober for a whopping three months after divorcing a recovering alcoholic wasn't the only thing Katy Perry did on 'Chatty Man' this week. She also sang!

Katy Perry and John Mayer's duet 'Who You Love,' which appears on his album 'Paradise Valley,' will be the singer-songwriter's next single. Since it's a single, it has to have its own accompanying cover art and it features the couple posing in romantic fashion.

The 2013 American Music Awards were rife with amazing performances from Katy Perry, Ariana Grande, One Direction, Rihanna, Miley Cyrus, Justin Timberlake, Christina Aguilera, Pitbull featuring Kesha and more. And you can catch them all here!

The 2013 EMAs, held in Amsterdam today (Nov. 10), saw celebs in a variety of different outfits. There were more cute, edgy dresses than there were fancy, couture gowns, since it's a fun, less formal event. The stars dressed accordingly and they all looked faboosh in their own, unique way.

Get your Kleenex ready. A terminally ill teenage girl sang 'Roar' by Katy Perry, it went viral, and, well, yeah. It's heartbreaking and inspiring at the same time. 16-year-old Olivia Wise, suffering from an inoperable brain tumor, belted out the tune, and her loved ones made her Internet famous for it.

Katy Perry has been vocal about the sadness she faced when she split with husband Russell Brand after only 14 months of marriage. But she is pulling back the curtain on details, revealing that she was so depressed that she holed up in bed for two weeks once Brand revealed he was done with the union.

Courtney Love has been in the business a long time, so she surely knows that one way to stay relevant is to talk trash about today's most popular artists.

Katy Perry covers the November issue of W. But it's not just Perry. It's Perry and her cleavage and her bodacious boobies. So it's all three of them gracing the cover. There's also a second, face-focused cover, pictured below.

Katy Perry was a tigress on the U.K. edition of ' X Factor,' performing on the show dressed like one.

Katy Hudson and Kate Hudson are BFFs! Wait, who's Katy Hudson? Oh, that's just Katy Perry; it's her real name. She was born Katheryn Elizabeth Hudson but uses her mom's maiden name professionally.

Congrats to Katy Perry, as her new album 'Prism' debuted at No. 1 on the Billboard Top 200.

We think Katy Perry needs to clear her dance card when she sees this adorable video in which openly gay Army Ranger Ken Yasger invites her to his upcoming Army Ranger Ball.
