How far should actors and actresses be willing to go to advance their careers?

The former “Wizards of Waverly Place” star is growing up fast. In fact, a source recently told Hollywood.com that the 2o-year-old actress is open to doing topless scenes “if the role was right.” The source added that Gomez is trying to be a “more serious actress” and wants to take on roles that separate her from her “Disney past.”

It seems that Gomez is trying to redefine her career in both movies and in song. In March, Gomez appeared in “Spring Breakers,” a film that features four teenage girls who find themselves in jail after robbing a restaurant to get money for their spring break trip. And, the actress’ recently-released single, “Come & Get It,” has a sexier feeling than her previous music.

Besides Gomez, there are a lot of actors who have been willing to go the extra mile to make a film role special. Check out Business Insiders’s “10 Actors Who Have Drastically Altered Their Appearances for Film Roles.”

Natalie Portman, for example, lost twenty pounds and practiced ballet for six months to take on the role of a ballet dancer in “Black Swan.” Christian Bale, on the other hand, lost 63 pounds to play an insomniac machine worker Trevor Reznik in “The Machinist.”

In other Gomez news, the actress recently welcomed a baby sister into her life. According to the New York Daily News, the “Come & Get It” singer’s mom, Mandy Cornett, gave birth to a baby girl on Thursday with husband Brian Teefey.

Gomez was undoubtedly thrilled by the birth of her first sibling, having tweeted to her followers on Mother’s Day that “mommy’s carry my baby brother or sister. I’m the happiest girl in the world.”
