Selena Gomez, 30, made her acting debut at age 10 and worked in different children’s series until Disney took her to the top with roles in The Suite Life of Zack and Cody, Hannah Montana and Wizards of Waverly Place. In 2009, this woman of Mexican descent launched her career as a singer. With nine albums under her belt, she went on to create her own clothing line, Dream Out Loud, and a perfume with her name, as well as several collaborations with the most popular fashion brands. She has been an ambassador for Unicef since 2009 and recently founded Wondermind, a mental health site that raised US$5 million from Serena Williams’ venture capital firm, Serena Ventures. The startup was valued at $100 million.
