45. Lady Gaga

It’s easy to be blinded by Lady Gaga’s flashy look and extravagant outfits, but the sensational singer is not all about putting on a show. Although her reputation suggests otherwise, Lady Gaga uses her fame to pursue meaningful causes, her main interest being the issue of bullying.

“Born This Way” isn’t just a song where she preaches for people to accept her (and others) as she is. The singer also started an organization in 2011 under the same name – Born This Way Foundation – an anti-bullying non-profit organization she co-founded with her mother, which aims to support and inspire youth and provide them with life-skills.
