TVGuide.com: We caught you smack-dab in the middle of your tour. Think you'll make it to Sept. 25?
Hilary Duff: I am going to make it, yeah. I'm doing good. It's lots of fun!
TVGuide.com: What is the hardest part about being on road for 2½ months?
Duff: Living out of suitcases, definitely. I really dislike that part.
TVGuide.com: But don't you have a team of people to tote your clothes around for you?
Duff: Of course I'm not lugging my luggage everywhere; I have help getting it in and out of cars and stuff. But trying to stay organized and keep tabs on where everything is [is a pain].
TVGuide.com: What are Hilary Duff's dressing-room "must haves"?
Duff: I don't really have a big, what do you call it, "rider." [amenity and food demands] I don't have a big rider.
TVGuide.com: But c'mon, M&Ms, Diet Coke...? What's your poison?
Duff: No, I don't drink soda. I like hot tea, water... sometimes candy. Sometimes I crave chocolate a lot. But we have catering and at some of the stops, we'll find a restaurant and order in for everybody. I also like Fruit Gushers and pickles — those are my guilty pleasures.
TVGuide.com: You were pretty busy even before the tour started. In June, you filmed Material Girl, with your sister, Haylie. Tell me about that.
Duff: It was awesome. It was so much fun working with my sister.
TVGuide.com: Had you kinda had enough of her, though, by the end? You can tell me.
Duff: No! [Laughs] She's like my best friend. We don't get to spend as much time together now that I travel so much and she's working a lot, so working together was really cool. We shared a trailer and everything.
TVGuide.com: Shared a trailer? Such non-diva behavior!
Duff: There were two trailers set up for us, and we were like, "What are these for? We want to share a trailer." They thought we were crazy, but we had fun.
TVGuide.com: You've been dabbling with television; anything new coming up this fall?
Duff: I did Joan of Arcadia and George Lopez — they were fun little guest spots. But my birthday is coming up and I've been working for, like, a year straight, so I'm going to take a little break. I'm going to focus on the music and hold off until I find a movie that I really love.
TVGuide.com: After Material Girl, you shot Cheaper by the Dozen 2...
Duff: All the same people are in it, so it was great to see everybody again. I shot it for like 14 days before my tour, then I went back to L.A. to rehearse [music] for like a week, then I kicked the tour off. I toured for about two months and then flew to Canada for about three days to wrap my work on [the film].
TVGuide.com: Is there any special reason we're revisiting the Bakers' Dozen?
Duff: [The parents played by] Steve [Martin] and Bonnie [Hunt] feel like all their kids are growing up so fast, so we take one last trip over the summer to the lake house we've been going to for years.
TVGuide.com: Are you excited to be hosting the Teen Choice Awards with Rob Schneider?
Duff: Very! I'm also a little nervous, though, because I only have one day to rehearse and get the dialogue down. But I love the Teen Choice Awards.
TVGuide.com: That's the one with actual surfboards for awards, right? I always wonder, where do these celebrities keep them? The garage?
Duff: [Laughs] You hang them on a wall! I think everyone who has won awards and stuff has some kind of little room dedicated to the awards. Or your garage, that's a good place, too.
TVGuide.com: The Still Most Wanted tour ends right before your 18th birthday. Do you have any special plans lined up?
Duff: I'm not sure what I'm doing. I know I want to go on vacation and get away from everything, get away from the crowds of people.
TVGuide.com: I guess that rules out the surprise party at Chuck E. Cheese that Haylie was plan--. Oops! Ignore me.
Duff: [Laughs] That'd be fun, I'd probably like that better than some big Hollywood extravaganza!
