Standing in front of a huge crowd at the MTV Movie Awards? No sweat. Introducing a scary movie tribute at the Oscars before tons of Hollywood icons? NBD. Kristen Stewart has no problem calming her nerves for things we'd be totally freaked out about, but when it comes to karaoke, she's running for hills.

Although the 20-year-old actress effortlessly played a rockstar in her film the Runaways, Kristen recently admitted she's petrified of the musical activity. "I would never, ever do karaoke. I am so scared of that," she said. "Each time I have ever given it a try I have had about two lines and I have ended up talking them. It's making me embarrassed just talking about it."

So, we guess we won't be challenging Kristen to a Karaoke Revoluton Glee battle any time soon. We're kind of shocked that the Eclipse star hasn't completed a whole song, especially when she seems so comfortable on the mic in any other public situation. But then again, we know KStew likes her alone time, and even calls herself "a crazy cat lady" because she prefers to stay home with her pets. What about you? Are you a fan of karaoke?

Kristen Stewart ruined some great photo opps by skipping out on the 2010 Teen Choice Awards on Sunday. Her Eclipse co-stars Robert Pattinson and Taylor Lautner managed to show up, but KStew was totally MIA. What's the deal?

Kristen had to miss out on all the TCA action because she was on location in Montreal filming her new movie On the Road. The 20-year-old actress has been cast as Marylou in the screen adaptation of the classic Jack Kerouac novel of the same name, and will reportedly shoot in the Canadian city for 45 days.

Even though she was nominated in five categories (find out if she won here), it seems Kristen had a pretty good reason to miss out on one of the biggest award shows of the year. However, Rob is currently busy filming his new flick Water For Elephants, albeit in L.A., and he was able to squeeze in the appearance. (Oops, thanks to one of our readers, we now know Rob's film wrapped on August 5.)

Kristen Stewart's dating Robert Pattinson, but there's another guy in her life who she considers herself "obsessed with."

Who's the mystery man that stole Kristen's heart? Her cat Max, who's pretty much her BFF.

"I'm so boring. No I am. I sit in my house with my cat. I'm a crazy cat lady, just give me a couple of years," Kristen dishes.

Max travels to stay close to his famous owner -- although it doesn't seem like he's the biggest fan of flying. KStew spills, "I really like him. It's frustrating when you travel, though, and especially because my cat is insane. He sits in a carrier under the seat in front of me on a plane, but it's really not cool to have him in the cabin because he screams and rips his claws out."

Rob's an animal hugger and lover, too, and adores his pooch named Patty Pattinson. Do you think this famous couple arranged a pet play date yet?

Eclipse had a huge opening weekend, and Robert Pattinson and Kristen Stewart couldn't be more grateful for their fans. So, as a special treat to their Twilight devotees, the two Eclipse stars showed up at a theater in L.A. to say express their gratitude in person.

Both Rob and Kristen were introduced before a surprised and screaming audience after a showing of their brand-new film. "We just wanted to come say thank you in person for making it such a great weekend, and we really hope you liked the movie," Kristen said.

"I hope you liked the movie, because otherwise this would be really embarrassing," Rob added. The appearance was part of a small tour in which 20 cast members visited theaters around the U.S. to show their appreciation for their fans.

How cool is that? We're really surprised Rob and Kristen didn't get mobbed, and by the looks of the video footage, which you can watch after the jump, it doesn't seem like they had much security. Did you go to Eclipse this weekend in hopes of seeing one of its stars?

We have some Twilicious news for you: Taylor Lautner could be catching a screening of Eclipse at your local movie theater this weekend.

Buh-bye brown, and hello red! Kristen Stewart made heads turn at the Late Show With David Letterman when she showed up with a whole new look. The Eclipse star arrived at the New York City appearance sporting shorter, auburn hair.

So what's the deal? We're used to Kristen's layered rocker look, but all of a sudden she decided to chopped off several inches and dye her hair a coppery red. Well, according to People, the cut-and-color move was for her upcoming role as Marylou in the movie adaptation of Jack Kerouac's 'On the Road.'

Demi Lovato just lightened up and added blonde highlights to her hair for a new summer style, and we're sure more stars will do the same. But given Kristen's tomboy ways, she was probably the last person we expected to switch things up.

What do you think of KStew's new 'do? Are you all about her lighter tresses or would you rather see her back to her brunette ways? Check out her hair from multiple angles in our photo gallery below and let us know what you think in the comments below.
