Miley Cyrus is 18. The "Hannah Montana" star is finally able to vote, and that means she has a whole future ahead of her in the world of music and movies. As 2010 wraps up, it seems that 2011 will be just as busy for the teen star, and while she's taking a break from music (not that you'd be able to tell, thanks to her bevy of music videos and awards-show performances), she has a bustling film career for fans to follow in the coming 12 months.

Cyrus recently wrapped her Ashley Greene co-starring flick "LOL: Laughing Out Loud," which saw the star not only filming Stateside but also in Paris. The movie follows teens who rely on the Internet to socialize, leaving their parents (Miley's mom is played by Demi Moore) confused by the modern relationships their children are in.

"[Miley] is a true professional, and she truly has a wonderful family," Moore said about her teen co-star. "It really shows." The veteran actress plays the overbearing, confounded mom of Cyrus' character, who gets freaked out after accidentally reading her daughter's journal and finding out just how out of touch they have become.

Miley is also getting ready for some action for her next role in the flick "So Undercover," where she'll play "a tough, street-smart private eye hired by the FBI to go undercover in a college sorority." The flick means that the star will have to learn to fight for the role.

"She's basically this chick who grows up as a super tomboy, and she's an FBI agent and gets thrown into a bunch of girls that she doesn't understand because she's been around her dad, who's been in the FBI his whole life," Miley explained. "And basically, by having to go undercover and be someone that she's not, she kind of finds the person she is, because she realizes she doesn't have to carry the weight on her shoulder of what her dad was, and she can be her own person."

While Miley has finished shooting "Hannah Montana," her hit Disney series won't go off the air until 2011. "I think that she's growing with the show, and I think it's such a great platform for her," her pal Selena Gomez told MTV News about the star's plans to walk away. "And she's lived up to it as wonderfully as she could, and I think she continues to carry it, but she's ready for other things."

Until then, Cyrus will hang out with her family for her big day, something that she was looking forward to the last time we spoke with her.

"I'm not going to go crazy; [just] have a fun party and then maybe take a vacation with my family ... because that would be really cool. I think we need time to all be together," she said. "So that would be rad if we could all go to the beach or something. ... [I have] no idea [where we're going]; somewhere near water. I'm a water baby; I have to be near the water and I love doing scuba and going out and being on a boat."
