There are more than 31 million Mexican-Americans living in the United States, a substantial and strong part of the fabric of the US. Here’s a quick look at 10 famous Mexican-Americans:

One of the current wave of teen stars, Gomez is a dual threat: she can sing and she can act. Gomez, who first burst on the scene in the Disney Channel series ‘Wizards of Waverly Place,’ is also the envy of many a teenage girl, courtesy of her relationship with pop icon Justin Bieber. She also likes to give back to the community — in 2009, at the age of 17, she became the youngest UNICEF ambassador ever.

Like Gomez, Lovato is another teen queen who sings, acts and got her start on Disney, with her lucky break coming on the series ‘Sonny with a Chance’ and in the ‘Camp Rock’ films. Despite the fact she has yet to finish her teenage years, Lovato has already overcome a lot of adversity. In late 2010, she cut a tour short to receive treatment for bulimia and intentionally hurting herself. She also revealed she was diagnosed as being bipolar and needed help after essentially having a “nervous breakdown.”
