Katy Perry

Why so serious? John Mayer and Katy Perry looked pretty sad leaving Mayer's 35th birthday dinner at Freeman's in NYC last night (Oct. 16). Is the thought of aging setting in? Was the clam dip bad?

Ouch. Remember back when Travie McCoy of Gym Class Heroes and Katy Perry were the cutest couple on the block? (It's okay, we forgot, too.) Turns out Perry actually sent McCoy packing ... over email.

It's been a while since Travie McCoy from Gym Class Heroes and Katy Perry were an item, huh? We kinda almost forgot they were a couple long ago, but since breaking up and her marriage (and divorce) from Russell Brand, McCoy has opened up about his time with his ex.

Katy Perry showed her support for incumbent president and 2012 hopeful Barack Obama at a recent fundraiser, performing not only her own hits, but also a cover of the Al Green's classic 'Let's Stay Together.'

Katy Perry goes Old Hollywood glam in the latest campaign images for GHD, a line of hair products and tools. These images are more glamorous and sophisticated than previous campaigns, but Perry looks just as gorgeous. Her hair is like a diamond in the light, since it's so rich and luxe.

No real surprises for best dressed at the 2012 MTV Video Music Awards. Check out these pictures of fashionistas Rihanna, Katy Perry, Pink, Demi Lovato, Rita Ora and Kesha... wait, Kesha? OK, maybe there were some surprises.

According to NPD Group, research shows that there are at least 500 celebrity fragrances released each year. That’s quite an obscene number since… well, are there even 500 celebrities worthy of fragrances out there? Of course with each new fragrance comes the expected Best and Worst lists, and sadly, Katy Perry‘s fragrance “Purr” made the latter.

John Mayer once referred to his ex Taylor Swift writing about their relationship and their split in a song as “cheap songwriting” but we’re going to call his method of dumping Katy Perry (after a very short and public romance) a cheap move. Mayer reportedly broke up with the ‘Wide Awake’ singer via email.

Sure, Kristen Stewart cheats on Robert Pattinson in a major way and now the guy is attached to all of the hottest women in Hollywood. First it was Rihanna, but now, he’s set his sights on RiRi’s BFF Katy Perry!

All eyes are on the seemingly budding romance between singers Katy Perry and John Mayer, who’ve been seen around town in Hollywood hotspots like the Chateau Marmont, which is where celebs are “supposed” to go to have some peace and quiet out of the public eye, yet they are always photographed there because the paparazzi know about it. However, the relationship between the two might not be as new

Katy Perry and Russell Brand split at the end of 2011, and since then, they’ve each moved out of the marital abode and into new digs. That’s not shocking, since they likely wanted to get away from the memories of their marriage and start fresh somewhere else, without any emotional baggage in terms of real estate. Brand moved out first and now, Perry is renting a crib in Hollywood to the tune of $8

Katy Perry may not have had a blockbuster on her hands with her ‘Part of Me‘ film, but that doesn’t mean movies and TV aren’t still on her radar. The ‘Wide Awake’ singer wants to expand her acting resume.
