The most powerful female celebrities of 2012 is a list that encompasses all the women in Hollywood who use their power for something other than getting ahead in the industry. At the top of the list is Oprah, who has increased her media presence with her own network OWN, and has brought in the biggest audiences to the network through exclusive interviews with the biggest stars in the worls (such as Rihanna, Whitney Houston's family, Michael Jackson's family, etc.) Winfrey will also return to the big screen in 'Butler', after many years of not acting.
At number 2 is Lady Gaga - need we say more? Her album 'Born this way' has been a smash success, she's started her own non-profit organization, and she continues to work with the MAC Aid Foundation.

At number 3 is Beyonce, which again probably doesn't need words to explain why she's on this list. As one of the most successful female musicians in the world, she commands attention and respect everywhere she goes. She has also entered the non-profit world, having partnered with the National Association of Broadcasters Education Foundation, a non-profit that focuses on diversity and community service in the media.
At number 4 is Jennifer Lopez, at number 5 is Shakira, at number 6 is Ellen Degeneres, at number is Angelina Jolie, at number 8 is Sofia Vergara, at number 9 is JK Rowling, and at number 10 is Giselle Bundchen.
