Here is Kristen Stewart outside of the Ed Sullivan Theatre on Monday evening, about to be interviewed by David Letterman. She lightened her hair. She had been rocking various dark brunette shades for the past few years, as she’s endlessly been playing roles that required it, first as Bella and then as Joan Jett. So, what do you think of this red shade? I’m calling it red, but some are calling it strawberry or cherry or blonde or whatever. To my eyes it’s red with some blonde highlights. I do think it looks good on her – it “lightens” her look in a lot of ways. For one, she doesn’t seem like a faux goth chick trying too hard. Also, it compliments her skin tone. And everybody notices the redhead!

I was looking around for interesting stories about Kristen and I found this kind of funny interview she did with People Mag about her feet and her shoe drama:

What happens when you promote not one, but two films – on back-to-back red carpets? For Kristen Stewart, the result is a severe case of the high-heel blues.

“I feel like my feet are really pissed off at me, just because of the shoes,” Stewart told PEOPLE at the premiere of her new indie drama Welcome to the Rileys on Friday. “That’s been the biggest problem.”

One night earlier, the actress, 20, strutted the carpet at the L.A. premiere of the new Twilight film, Eclipse, which she has been promoting around the world. But she says she’s not exhausted by the publicity grind – much the opposite, in fact.

“By the end of the day I actually get really hyper, because it’s then that I have my own time,” she says. “You end up staying up all night and then screwing your morning the next day because you need time to yourself.”

As for her intensely emotional role in Rileys, in which she plays a teenage prostitute, “the subject matter was a lot sadder and emotionally distraught than I’ve ever had to deal with,” says Stewart. “It’s sort of the lowest of the low that I’ve ever had to go.”

Is she worried about how Twi-Hards will respond to seeing her in such a different role?

“Luckily Bella wasn’t my first part,” she says. “I’ve had the chance to really get comfortable with keeping true to why I do what I do, and I can only do it this way. I’m proud of myself – so if other people aren’t, that’s totally cool.”

She also told People Magazine that the great love of her life was her 6-year-old cat, Max. She says: “We have a really strong, really weird codependent, almost Bella/Edward relationship. I’m going to be a crazy cat lady one day, I’m sure.” I grew up with cats, a fact that my mom now bemoans every time I tell her a story about my dog. She always sighs and says miserably, “I can’t believe I raised a dog person.” In truth, I still love cats, and I would love to have one and just live it up as a crazy cat-and-dog lady, but my puppy is so possessive, and I think he would probably eat the cat.
