Kellan Lutz for PETA: Clothed, Pushing for Adoption

Come on, Kellan Lutz.

It's not enough that you have a ridiculous body? You also need to love animals and pose with puppies more adorable than all the Twilight Saga stars combined?

The actor stars in a new PETA campaign. Unfortunately, he isn't naked, like so many other animal-loving celebrities have been when appearing in ads for this organization.

But Lutz still has an important message to send, as the poster below reads: “Buying Animals Is Killing Animals. Save a Homeless Dog or Cat - Always Adopt and Never Buy.”

Said the actor:

"There are surprisingly so many animals in these animal shelters. It’s sad, and knowing that they get euthanized... and there’s a lot you can do... spay or neuter your pets so that doesn’t happen.”

Audrina Patridge, Ryan Cabrera Film The Hills

Audrina Patridge and Ryan Cabrera are not only an item, they're co-workers. Well, kind of. For her, "work" is being on MTV's non-reality show The Hills.

It looks like Cabrera has agreed to come on board the long-running program, filming scenes last Friday evening at Hollywood club La Vida with Audrina.

The two were being filmed "for about an hour at a secluded table on the patio," according to witnesses. Wonder what the cue cards had 'em talk about.

A rep for Ryan Cabrera confirmed that he'll appear on the show, but hasn't yet signed a deal. Looks as though his career is "On the Way Down." Sorry, had to.

Having dated years ago, the singer and reality star rekindled their romance in January. The two were seen holding hands in Mexico earlier this month.

"Ryan is a great guy," a pal tells Us. "Audrina is having fun!

It's easy to see why. He seems chill, and Patridge's most famous Hills romance was with that douche Justin-Bobby. From there, one can only improve.

Other men in her life haven't been that much better. Corey Bohan fizzled out, and Zachary Loring, well ... he's certifiably insane and stalks her a lot.

Charlie Sheen: Also Off to Rehab

The Sheen family takes a very different approach to rehab than Amy Winehouse.

With wife Brooke Mueller checked into a treatment center for substance abuse, Charlie Sheen's rep has confirmed that his client has also entered a facility as "a preventative measure."

"He will take some time off his series Two and a Half Men," the rep added, not elaborating on why Sheen is in rehab.

The actor is facing domestic violence charges as a result of his Christmas Day confrontation with Mueller. He's expected in an Aspen court on March 15.

Sheen has reportedly attended rehab programs at least twice before to battle drug and alcohol problems. A source tells People this stint relates to the fallout from the domestic violence case, however.

"Charlie is stressed. He's tired. The kids are on his mind. Brooke's on his mind," the insider said. "A lot of things are on his mind. He didn't want to get a place where he had the urge to get high. He's not using and he doesn't want to. He felt like he needed to get away from negative influences around him and clear his head, rest and take a short break."

Sheen will remain in the facility for two weeks.
