8. Ariana Grande, 22

Ariana Grande started in the humble sidekick role on a Nickelodeon kids’ show, but that was just a warm-up. So long, ditzy Cat Valentine, hello Ariana Grande: superstar! She is only 21 years old, but she is a powerhouse performer, selling out shows and belting out lyrics and notes that only the most talented singers could muster. Way back in the day when she was 10 years old, Ariana was a co-founder to Kids Who Care, a youth choir philanthropy organization, which raises money for charities. She also speaks out against cyber-bullying and supports veganism. Oh, and she teaches little African kids how to dance!
