It’s Pop Week here at MTV News, and that means we’re catching up with and getting to know everyone who’s going to make a splash in pop music and culture over the next 12 months. Whether they’re just arriving on the scene or are already the name on everyone’s lips, these are the artists we expect big things from in 2009.

These are the queen bees of the teen-queen pack. You already read their names almost every day, and they’re keeping busy in 2009 so you won’t forget about them anytime soon. With upcoming movies, music, books and clothing lines, these girls know that it takes a lot more than just being a triple threat to be famous — you need to do everything possible to stay famous.

Here’s what your Female Pop MVPs will be up to in 2009:

She may have lost at the Golden Globes , but Miley Cyrus doesn’t seem like she’s going anywhere anytime soon this year. Her autobiography, “Miles to Go,” hits bookstores in March. Cyrus will continue her role as Hannah Montana, both on the small screen and the big one. Cyrus is following “Miles to Go” with the release of the “Hannah Montana” movie in April, which is sure to get fans excited. In the film, Hannah heads home to Tennessee, where she’ll sing some songs, fall in love and hang with Dolly Parton. On top of that, Cyrus will begin work on a film based on a Nicholas Sparks novel .

2009 has already been busy for Taylor Swift, who just finished work on the video for her single “White Horse.” “This video is a lot different than the other videos that we’ve made, ’cause usually we’ve gone for bright colors and me looking straight into the camera and singing,” she said of the clip. She is also ready to film her cameo on “CSI,” and, according to her MySpace page, she’s getting ready to tour in support of Fearless. The album’s success is still flooring Swift, who can’t believe it’s sold more than a million copies since its release in November. “The fans have been so good to me,” she told MTV News. “The fact that people actually like it, I can’t believe it.”

Katy Perry kicked off 2009 by announcing her split from longtime beau Travis McCoy . Now the “Hot n Cold” singer is gearing up to hit the road for her Hello Katy Tour. “It’s a new year, and I’m very focused,” she told MTV News. “I’m putting all my energy and efforts into [the tour].” On top of that, the 24-year-old has the Grammy Awards in February. But, like everyone else, Perry isn’t really sure how she can follow up a smash year like 2008. “I’m kind of just putting one step in front of the other, and I never expected any of it to happen, so I don’t expect it to always happen perfect every time, you know?” she said. “I’m constantly knocking on wood and freaking out saying, ’Really? They want me to do that?!? OK! Really?’ ”

Yeah, we all know Stewart will be hard at work on “Twilight” sequel “New Moon” in 2009, but the girl known as Bella Swan also has a slew of other projects this year that are sure to solidify her status as a Hollywood “it” girl. Twilighters can catch Kristen in several films , including “Adventureland,” in which she plays a rocker chick, as well as “Welcome to the Riley’s,” in which she plays an exotic dancer. She was also hand-picked to play Joan Jett in a Runaways biopic.

Aubrey O’Day
In 2009, we are going to see a lot of Aubrey O’Day — especially now that she’s going au natural for her big Playboy shoot . But don’t think that’s the only thing the former Danity Kane member has in store for the new year. “I’ve been able to move forward with a lot of the solo projects that I’ve had in my heart, including, obviously, music,” she told MTV News. “[I’m] also doing reality TV as well and some movie projects.” Those projects aside, O’Day is definitely hard at work on her solo album. “I’m keeping true to the Danity Kane roots with the R&B/pop roots but taking more of a rock-electronic edge to it, and I’m a little rocker in my heart,” she said. “I think it’s going to be fun, danceable music that is outside of the box and allows you to express yourself in any way possible, which is exactly who I am as a person.”
