Selena Gomez

At 17, Selena Gomez is already an actress, singer and now... philanthropist. On Sunday, the star of Disney's Wizards of Waverly Place will be on hand to meet the Scott family, who learns that their problem-ridden home will be rebuilt by ABC's Extreme Makeover: Home Edition (8/7c). TVGuide.com spoke with Gomez about her passion for giving back to her community and what's next for her on Wizards.

TVGuide.com: How did you get involved with Extreme Makeover: Home Edition?
Selena Gomez: The little girls in this episode were big fans of the show. They didn't know where they were going and they just pulled up [to the Wizards set] and were completely surprised. We gave them a huge tour of the set. It was awesome.

TVGuide.com: What was it like to be a part of something so special?
Gomez: That's one of my mom's favorite shows — she cries every time. We've always watched, so it was an honor.

TVGuide.com: Are you involved in any other volunteerism?
Gomez: Radio Disney is having this contest called "Give Back." The winner will fly to California and with me, go to the UNICEF office and donate $5,000. Being blessed to have a voice and using it for causes that are important to me and educate kids my age about everything going on outside of either our country or even the next state over — I'm honestly the luckiest girl in the whole world.

TVGuide.com: What's up next for Wizards of Waverly Place?
Gomez: We are on Season 3 right now, so we have a lot more magic. My character, Alex, has a lot of growing to do and she falls in love for the first time. [Gomez's love interest is played by British actor Gregg Sulkin, who stars in Disney Channel U.K.'s As the Bell Rings.]

TVGuide.com: Do you have a favorite spell or ever wish that you could actually perform one of them?
Gomez: Each of the spells I use makes one of the cast members go, "Man, I wish I could do that." I mean, what kid wouldn't wish they could rewind time or be invisible? I love that we're able to bring all those things to life on the show.

TVGuide.com: Is it harder to maintain your privacy now that you have such a large fan base?
Gomez: Just a little bit, but I think that I can speak for my cast as well, that we obviously haven't forgotten that they're the reason why we're here, so we would never once complain about that.

TVGuide.com: Your band, Selena Gomez and the Scene, recently released an album. How's that going?
Gomez: It's going really well. It's my debut album and we're able to tour it on the weekends. My fans from the show are being really supportive of my music.

TVGuide.com: Touring while filming a TV show has got to be exhausting.
Gomez: It is hard. I figure while I'm young I guess I can do it — take advantage of my age.

TVGuide.com: Would you and [Gomez bestie] Demi Lovato ever tour together?
Gomez: That would be awesome. I'm doing my show and she has her show, but that would be fun.
