2. Lady Gaga
Lady Gaga has long been a vocal champion of the LGBT (lesbian, gay, bisexual and transgender) community. While the singer has participated in countless charity initiatives to help the cause, one of her most talked about ones was the time she auctioned a nude portrait of herself on eBay, raising money for her Born This Way foundation for young people in the LGBT community. In 2012, Lady Gaga received the Trevor Hero award for her work.
