When Selena Gomez started dating Justin Bieber, she was living out the fantasy of millions of young girls all over the world. She also incurred their fury. You don't get to go out with someone that every young girl fantasizes about without them resenting you for doing so! Mocking him after they broke up, and saying that she made him cry, made her even less popular with 'Beliebers.' She was also accused of having a one-night stand with Orlando Bloom, during a time the actor was dating Katy Perry.
Relationships may not be her forte, but inspiring children is. As someone who found fame at a very early age, Gomez considers herself to be fortunate, and has tried to improve the fortunes of other young people. She's one of the youngest people ever to become an ambassador for UNICEF, and has repeatedly campaigned for youth education and health programs. Through her own experience with the health condition lupus, she's also been credited with raising awareness about the disease.
