Hilary Duff talks about her new movie, War, Inc., during MTV’s Total Request Live (TRL) at the MTV Times Square Studios on Tuesday in New York City.

In the political war comedy, the 20-year-old singer/actress plays the character Yonica. Said The Duffster, “It was such a trip for me to do this character because it was so different from who I am and even the way I looked in it–she has an accent, she’s Eastern European, she’s a little oversexed, super young, she doesn’t know what she’s doing. And the way she dresses is really cheesy and out of control. It was fun for me to do something so different from who I am.”

John Cusack wrote, produced and starred in the film, which comes out in theaters on Friday, May 23.

Iron Man stars Robert Downey Jr. and Gwyneth Paltrow promote their latest superhero flick in New York City on Monday afternoon.

The pair stopped off at MTV’s Total Request Live (TRL), which will air on Thursday. Gwyn continued promoting at The Late Show with David Letterman, which airs tonight. You can also watch Robery Downey Jr. om Good Morning America here.

Iron Man has scored a healthy 82% on RottenTomatoes.com so far. Solid reviews across the board and Just Jared can attest to them!

I saw a screening of the film over the weekend and I can vouch that Robert Downey Jr. IS Iron Man. He does such a fantastic job of portraying multi-zillionaire industrialist Tony Stark with charm, wit and humor. And the special effects? Fuhgeddaboutit. Fan-freaking-tastic!

After rapping for Nelly, Heidi Montag leaves MTV TRL Studios in Times Square, New York City on Monday.

Earlier this month, Heidi, 21, declared her support for John McCain, but had not yet registered to vote.

But she recently told MTV News, “I am definitely registering to vote. I’ve just been so busy and crazy filming and working on my album and working on my fashion show that I’ve hardly had any time,” she said at the Heidiwood fashion show.

Heidi also shared about her aspiring movie career. “The perfect movie I want to do is like [Jennifer Garner’s character] Sydney Bristow on Alias. I want to be, like, an action star. I want a big gun,” she laughed. “Like Angelina Jolie roles. I want to be the badass.”

She also turned down doing a movie for The Hills: “I’ve never discussed a movie possibility 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 a Hills movie, I wouldn’t be in it. No, thank you.”

The Hills‘ feminist hero Heidi Montag rapped during her guest appearance on Monday’s TRL. Here’s how her freestyle went, which rapper Nelly gave an “A” for effort:

Yo, yo
I got Heidiwood
I’m wearing it all day
I like it, so what do you got to say
You got apple bottoms, what
You know what’s going up
Um, keep going, I’ll keep flowing
You know what I like to say
Everyday, I’m in New York
It’s all good this way

Gossip Girl pretty boys Chace Crawford and Penn Badgley ham it up for the cameras during TRL at MTV studios in Times Square.

Penn wore cutie Calvin Klein underwear!

The trio dished the dirt on each other, revealing what they “really thought about each other.” Ed apparently is a musician and is part of a band back in the UK. Between the three of them, Penn is the biggest player, Ed watches the most chick flicks and Chace? Well, he got burned. He apparently spends the most time in front of the mirror, likes the worst music, tells the worst jokes and takes advantage of the most celebrity perks! Ouch!
