Katy Perry

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 CAUGHT LIP SYNCHING IN FRANCE - WATCH THE CRINGE WORTHY PERFORMANCE: KATY PERRY'S lip-syncing fail might be the most awkward thing you see today. Katy was performing at the NRJ Music Awards in France, and was very obviously just moving her mouth to a track. I say 'very obviously' because the vocal track is clearly out of alignment with her singing.

The 2013 American Music Awards were pretty innocuous and safe, in terms of pop star antics. There was no tongue-and-twerk craziness and things were tame for prime time, network TV. However, the broadcast was not without controversy, as Katy Perry was accused of racism after her performance of 'Unconditionally,' which featured the singer dressed as a geisha.

IS THAT AN ENGAGEMENT RING ON KATY PERRY'S FINGER?!: Are JOHN MAYER and KATY PERRY engaged?! That's the hot, new rumor after Katy was photographed flashing a sparkly diamond on her ring finger at MTV EMAs.

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.

Bullying used to mean you got pushed up against a wall by a thuggy kid on the playground who then stole your lunch money.  But social media has taken bullying to a horrible new level, and El Dorado High School students say it has to stop.

Katy Perry, apparently forgetting her rise to fame involved talk of kissing girls and shooting whipped cream out of her bra, is taking other pop stars to task for nudity. Is she shading her BFF Rihanna or her Billboard competition Miley Cyrus?

It was an all-star jam at Katy Perry's We Can Survive charity show in Los Angeles last night (Oct. 23). The singer invited her guests -- Tegan + Sara, Ellie Goulding, Sara Bareilles and Kacey Musgraves -- to join her. They all sang along on the the epic, anthemic chorus and did their thing on the verses!

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.

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

Katy Perry has her name plastered on anything for a buck -- she's had deals with Wal-Mart, Cover Girl, Eyelure Eyelashes, PopChips, ProActiv, Adidas, GHD, OPI -- but it's her deal with Pepsi that's getting people's panties in a twist.
