Katy Perry to Teen Vogue, on fame:

Folks who enjoy experiencing Katy Perry on screens of various sizes, in fields of various dimensions are in for a treat this summer: she's coming to the movies in 3D.

Where do you go from a misguided cover of "Niggas in Paris"? Dissing Beyoncé sounds about right. While discussing a potential collaboration with Rihanna on BBC 1, Perry noted that she doesn't want to rush things. And then she got passive-aggressive.

In today's second edition of "Don't Make That Rap Video," Katy Perry covered Kanye and Jay-Z's "Niggas in Paris" over the weekend. It is obviously horrible, but it did leave us with a fascinating chicken-or-egg question: Did Katy Perry beget Karmin, the white-people-rappin' duo featuring Perry doppelganger Amy Heidemann on vocals, or did Karmin's insufferable covers beget Katy Perry trying to be more like Karmin?

I was watching the Grammys last night because I had nothing better to do, and it dawned on me that, for all of the Grammys' shortcomings (and there are many), I enjoyed watching that telecast FAR more than I've enjoyed watching any Oscars telecast over the past 10 or 20 years. Here's why:

After spending Christmas apart and being spotted in public without their wedding rings, Russell Brand made it official and filed for divorce from pop singer Katy Perry. He proposed to her on New Year's Eve 2009, so it's about exactly two years since they got engaged and a year since their October 2010 marriage.

Remember the awesome Halloween lights that danced to "Monster Mash?" Well, not to be outdone, this house has synced their Christmas lights to Katy Perry's "Firework." Amazing.

The Grammy Awards nominations were announced on Wednesday night! Hooray! Everyone loves the Grammys. They're like the Oscars for blind people. And your mom's entire iPod was nominated. Here are the nominees. Congrats, Skrillex! Exchange bitcoins accordingly.

Scotty McCreery misses his cue. Brad Pitt wasn't always a tragically overweight, dumpy-looking urchin with a comb-over. Kim Kardashian exposes herself to The Poors and learns the true meaning of Thanksgiving. Today's Gossip Roundup is sitting on the couch with some turkeys, playing video games and eating pumpkin pie topped with mashed potatoes instead of Cool Whip.

Just like everything else about her nuptials, it seems like Kim Kardashian jumped the gun ordering her holiday cards with her wedding photo on them. Kristen Wiig is hanging out in her undies. Katy Perry is not pregnant. Paz de la Huerta ruined the ending of Boardwalk Empire. Tuesday's gossip has been known to make mistakes.

Lady Gaga marks her dressing rooms with urine in surprising places. Jessica Simpson plans to give birth in 4-inch Yves Saint Laurent heels. Rihanna is horny and not getting laid enough. Nicki Minaj wants to use a vibrator in front of children. Friday gossip has needs.

She's been an alien, a nerd, the princess of Candyland, and with the video for her latest single, "The One That Got Away," Katy Perry plays a sad, wrinkly old grey version of herself reflecting on a passionate relationship gone sour.

We're judging every single one of Lindsay Lohan's court outfits, and boy have there been a lot! We also take on Katy Perry, Laura Dern, James Franco, and a host of other celebrities who couldn't get a good look together.

Finally getting hip to the fact that it is the world's sexual barometer, Google has introduced its own sort of gaydar, which will tell you which celebrities are gay and which are straight. But how reliable is it?

Royal horror: Pippa Middle got into an upskirt photo situation at London Fashion Week. Now, the simplest way to avoid an upskirt photograph is to wear longer skirts or pants. (Or live in a world with civility. Hah! Right.) Unfortunately, starlets live in a world where the skirts are short, the cars are fancy and difficult to climb out of, and cameras are everywhere. Consequently, starlets' vaginas are in perpetual peril. How do they deal with this? Now presenting the Seven Highly Effective Habits of Starlets With Cameras Pointed Up Their Skirts.

Now that Fashion Week is over here in New York, it migrated to London, where Pippa Middleton was giving everyone a show in the front row. Join us on our little internet talk show where we make fun of the outfits of Naomi Campbell, Katy Perry, Rachel Weisz, Kate Winslet, and a whole lot more. It's the hottest thing for fall.

Have you heard of singer Lana Del Rey? Well, probably not, because she doesn't even have an officially released single yet, but the hipster music blogs are all abuzz about her. Her music is great, but they still hate her because she's not "authentic." But that's not the problem at all.

America's national embarrassment will continue to take over our lands and townships with another song. Also today: bad news for Anderson, decent news for Sarah, and great news for twentysomethings.

The day after Russell Armstrong's suicide, his business associate also committed suicide. Matthew Fox's vagina-punch victim presses charges. Lady Gaga wears a prosthetic penis. Justin Bieber gets in a fender bender. Wednesday gossip is tawdry.

You thought you were done with Carrie B. and her shoe-loving ways, but you are not. Also today: J.Lo is officially in, ABC is maybe out, Sarah Silverman is in-demand, and Katy Perry is the best at being the worst.
