Earlier this month, The Hills' Heidi Montag, 21, declared her political support for Republican Sen. John McCain, but has not yet registered to vote.

She told MTV News that she's working on that.

"I am definitely registering to vote," she said.

"I've just been so busy and crazy filming and working on my album and working on my [Heidiwood] fashion show that I've hardly had any time at all."

Heidi Montag also talked about her film aspirations.

"The perfect movie I want to do is like [the famed Jennifer Garner TV character] Sydney Bristow on Alias. I want to be, like, an action star. I want a big gun," she said. "Like Angelina Jolie roles. I want to be the badass."

As for the frequently-discussed movie version of The Hills?

"I've never discussed a movie for The Hills ... and I'm not sure if for my first movie I'd let Lauren Conrad narrate me, so I don't think that would be something I would do. If I was doing movies, I'd want it to be with Denzel Washington or something like that. If they were to make The Hills movie, I wouldn't be in it. No, thank you."

We're guessing a fat paycheck could change that tune in about two seconds. We'll ask Spencer Pratt for his take on it in his next advice column.
