(Yahoo!) - Just like her uber-famous boyfriend Justin Bieber, Selena Gomez is ready to be thought of as more than just a squeaky-clean tween star. As the 20-year-old reveals in the new issue of Teen Vogue, she's itching to expand her resume beyond movies, shows, and albums aimed at kids. "It's frustrating whenever I want the roles that no one's even thinking about me for, and being like, 'No,' with all these other ones," she tells the magazine. "Being part of the Disney Channel was such a blessing, and I'm super happy with what ['Wizards of Waverly Place'] accomplished, but acting is something I would like to take on more seriously." Gomez's credits include projects like 2010's family-friendly "Ramona and Beezus," and guest roles on shows such as Miley Cyrus' "Hannah Montana," beginning with work on the kiddie program "Barney & Friends" when she was 7. However, Gomez admits that she still has a lot to do in Hollywood. "I don't necessarily feel accomplished. I want to create a whole different persona when it comes to acting."
