In today's Tweet Beat, Rihanna's stoked that people dig her on Instagram (RIP), the dudes from Chromeo are into Birkenstocks on women and Seth Rogen finds an ally in Patton Oswalt.

Seth Rogen and Zac Efron made an appearance on the Teen Nick show Ew! with someone who looks an awful lot like Jimmy Fallon, host of The Tonight Show. (WINK WINK.)

Seth Rogen stopped by Howard Stern this morning and talked about his run-in with La Biebz on a German talk show. He was NICHT IMPRESSED.

Prepare yourselves, because the Kimye Vogue cover parodies are coming. The muppets have already thrown down the gauntlet and now James Franco and Seth Rogen have taken up the challenge of becoming the world's most talked-about couple.

As the numbers of Alzheimer’s patients grow across America, it looks like us ladies are the most affected group in not one, but two ways: we're more likely to be diagnosed and be the caregiver when others are diagnosed.

There was absolutely nothing good about the announcement that certified awful person George Zimmerman (no celebrity bold for you!) would appear on an episode of Celebrity Boxing to square off against rapper DMX (on what would have been Trayvon Martin's 19th birthday, no less). This news was actually so not good that…

I normally don't like these types of parodies (I'M WEIRD I KNOW) but this one was pretty cute. The parody, produced by Alison G. Vingiano, Paul Gale and Daniel Hubbard imagines what it would be like if the film Her had been made with a male character as the sultry computer voice.

In today's Tweet Beat, M.I.A. is not lying about the facts, Seth Rogen and RuPaul forge a surprising relationship and Shia LaBeouf apologizes (again).

Just last week, the Internet got you a lovely gift: "Bound 2," starring Kimye, a motorcycle, a fleet of wild horses and the Grand Canyon. This week, the Internet got you something again. It is just so thoughtful. Here's the new gift: "Bound 2," recreated shot-for-shot with James Franco as Kanye West and Seth Rogen…

Turnz out everyone's favorite shirtless chest Zac Efron did a stint in rehab five months ago, while filming the upcoming Seth Rogen comedy Neighbors. E! claims it was for drinking, while TMZ says it was molly and coke — and that earlier this year Efron and some friends went on a flop-sweaty rager and caused $50,000…

Seth Rogen is officially old and making movies about what an old crank he is, if the preview for his new movie Neighbors is anything to go by. He and Rose Byrne play a married couple with a very cute baby that start to lose it when a fraternity moves in next door, headed up by Zac Efron. Also DAVE FRANCO ALERT HELLO.…

After engaging in some vintage Ross-and-Racheling over the summer, rumors are floating that John Mayer proposed to Katy Perry but she turned him down like a maid does beds in a Julian Fellowes drama. Way harsh, Tai. Popcrush reports:

In today's Tweet Beat, Seth Rogen has a useful skill that he's not sharing with the world, Amanda Bynes is the wisest sage on all of Twitter, and Snooki really reads books (obviously; she is a New York Times Bestselling Author).

This month saw the release of two Hollywood-centric films purporting to be set in the real world. One of them is an artistic tour de force about a group of friends who squabble, steal, and raid celebrity mansions in a haze of drugs. The other was directed by Sofia Coppola. (Interestingly enough, both films…

FINALLY. Remember Beyonce's regular body? The alive one that's all made of fat and muscles and full of organs? Guh-ROSS. Luckily, the ad wizards at Roberto Cavalli took care of it and are proud to present Beyonce: 2.0.

In today's edition of Tweet Beat, Seth Rogen got hit in the testicles by a dildo, LL Cool J chuckles to himself, and Robin Williams tweets the best conceivable response to Kim Kardashian's Met Gala dress.

Amber Rose says she was all set to have an at-home water birth, but at the last minute learned that her baby was breech and that she'd have to have a C-section on dry land instead. Stressful!

It's true, nothing gold can stay, and by "gold" I mean "Two and a Half Men, the worst CBS show you're not watching." While Ashton Kutcher and Jon Cryer have resigned their contracts for a third season (Kutcher at a $700,000-per-episode payout; Cryer at, I don't know, a gum wrapper and a damp Nickelback ticket stub?),

Here's the redband trailer for This Is The End, the Seth Rogen/Evan Goldberg directed movie slated for release in June. It's about six famous dudes — Seth Rogen, James Franco, Jonah Hill, Danny McBride, Jay Baruchel, and Craig Robinson — who get stuck in James Franco's house when Los Angeles starts crumbling around…
