Singer Katy Perry is friends with Kristen Stewart and Robert Pattinson, but when the collective Robsten broke up, Perry started spending a lot of time with Pattinson -- so much so that lots of people are wondering if they're hooking up. And Stewart is none too pleased.

...You read that right.

After they were seen canoodling at a party over Memorial Day weekend, rumors immediately ignited that Katy Perry and John Mayer were back together. While this was a rude assumption that assumed neither of them had the self-control to maintain a platonic friendship, well ... it looks like it's probably true.

Katy Perry has been a busy lady. In between platonic wedding-watching with Robert Pattinson, she managed to throw an A-list Memorial Day party -- and one of her invited guests was off-and-on boyfriend John Mayer. Cue the "oh no, not again" eye rolling.

Remember how Katy Perry, singer of binge drinking anthem 'Last Friday Night (T.G.I.F.),' called out rapper Chief Keef indirectly over Twitter after she heard his track 'I Hate Being Sober' on the radio? That didn't sit well with Keef, who isn't known for having the best judgment.

We already know Miley Cyrus is No. 1 on Maxim's Hot 100 list, since she blew up their spot over the weekend and revealed the big news before they did!

Katy Perry isn't a princess. She's a queen -- a Killer Queen, in fact. The singer is adding to her fragrance empire with a new scent, called Killer Queen. While her previous two perfumes Purr and Meow had cat themes, this one doesn't, although it does look a kitty-shaped adornment perched atop the red and golden bottle.

Katy Perry is hard at work on her third album, the followup to the smash 'Teenage Dream,' and she revealed that she treats her job like, well, a job: She sets her deadlines and meets them, or else. Oh, and her job is to write about double rainbows. Seriously.

Singer Katy Perry is known in part for her ever-evolving hairstyles, but that wasn't enough to extend her contact with the British hair care company ghd, which dropped the pop star as its spokesperson. The reason? According to ghd, she's just not as popular as she used to be. Ouch. That must burn like the worst curling iron mishap.

The Rob has shared some really great "Goat Editions" of various KISS-FM favorites, but I think I have found the ultimate "Goat Edition." Behold! Katy Perry's "California Gurls - Goat Edition."

It wasn't quite as revealing as the infamous Jennifer Lopez some years ago, but Katy Perry's choice of attire for this year's Grammy Awards certainly left little to the imagination and made John Mayer the envy of red-blooded men everywhere.

Katy Perry is considered one of the hottest women on the planet, so it may alarm a lot of our male readers to see how well she can pull off masculine drag. The 'Wide Awake' singer dressed like a man to celebrate Ellen Degeneres' 55th birthday on air, and it was possibly the least awkward she's ever looked while dancing.
