Stephanie Pratt, star of MTV's The Hills, bared her own buns for the cover of PETA's new "Be Nice to Bunnies" iPhone app, a searchable database designed by Hot Frog Creative that makes it a snap for shoppers to find cruelty-free products while they're on the go. The racy cover was deemed too risqué by Apple, though (it's OK to shed a tear) so we had to replace it with a PG version. Now the only place to see the controversial ad is here.

Want to know why Stephanie only wears fake fur and products that weren't tested on animals? Watch our exclusive interview with the future (fur-free) designer:

You can also enter to win some of Stephanie's favorite cruelty-free products. We love her—and we'd love it if you'd take her advice and follow PETA on Twitter.

Relationships on MTV's The Hills are unpredictable, to say the least. So, after having been on the show for five seasons, Audrina Patridge threw on a pair of angel wings and took her dog, Speedy Gonzalez, to pose in PETA's latest Angels for Animals ad. After all, a dog's love is absolute. They're never so fickle that they'd turn their back on you anytime some new guy walks into the room.

The ad was unveiled on a billboard in West Hollywood today, and Audrina was there to let people know that they should always adopt and never buy—because for every dog or cat bought from a breeder or pet shop, a shelter animal full of unconditional love will die.

Check out the event below and then enter to win autographed copies of seasons three and four of The Hills on DVD.

As a lifelong vegetarian, Jake Shields is no stranger to sticking up for the little guys. Maybe that's why the XC welterweight champion agreed to appear in a recent episode of MTV's Bully Beatdown, a show that puts teenage bullies in the ring with professional fighters to give them a taste of how miserable it feels to be the underdog.

In an interview with our friends at The Discerning Brute, Jake said, "Well I'm a life-long vegetarian and the diet obviously works. I also have two brothers that are strong and healthy. But you do have to have a good balanced diet and eat healthy foods. There's plenty of ways to get protein other than eating meat."

Awesome athletes like Jake and his fellow fighter Mac Danzig are evidence that not only is a vegetarian diet a possible diet for athletes, it might even be the best diet.

I’m going to shut up and let the man speak for himself here in a sec, but I feel like I need to admit that I spent pretty much my entire adolescence in a constant state of anticipation about what John Norris, Kennedy, Duff, or Jon Stewart (different incarnation) were going to say next on the popular music channel “MTV”. John is busy informing a whole new generation on MTV News, but he also took some time recently to talk to my star-struck friend Nicole Nuss about (among other things), why he doesn’t eat stuff made out of animals. The whole thing is just too cool for words.

Much as it pains me to pamper the egos of those too-cool-for-school scene queens over at peta2, I was really impressed with this interview that my friend Dan (who runs the show in PETA’s Youth Outreach division) just did with MTV Canada. I’ve been trying to get on MTV since I dreamed of auditioning for MTV’s The Grind in the early '90s (if you haven’t heard of that show, don’t worry about it. You’re better off.), but it looks like I’m going to have to settle for living vicariously through Dan’s achievement. Watch how he reels off hip bands like he’s Carson Daly or something.
