This is Gaga's second year in a row at the #1 spot. In 2011 she dedicated much of her time to putting an end to bullying and even started a new charitable organization called Born This Way. The "Marry The Night" singer did plenty more to help out those less fortunate in 2011, including auctioning off a nude sketch for charity and performing at the Bill Clinton Foundation fundraiser.
However, this was really Bieber's year to shine. He rocketed up DoSomething.org's list from #10 last year to #2 this year. It helps that Bieber donated some of his profits from his Christmas album, Under the Mistletoe, and his self-named perfume to various charitable organizations. Bieber also kept up his work with Pencils of Promise, a group that has built 41 schools in Laos, Nicaragua and Guatemala and was founded by his manager's brother.
Rounding out the top five were Will and Jada Pinkett Smith and Leonardo DiCaprio. This was a year for celeb power couples, with Brad Pitt and Angelina Jolie clocking at #8, Ashton Kutcher and Demi Moore at #12 and newlyweds Blake Shelton and Miranda Lambert at #14.
Other notable standouts this year were Demi Lovato at #10, Lea Michele making her charitable debut at #16, Daniel Radcliffe at #17, Miley Cyrus at #18 and Taylor Swift rounding out the list at #20.
