Beyonce and Angelina Jolie are among world's 100 Most Powerful Women

Beyonce and Angelina Jolie have been named among the 100 Most Powerful Women in the world in a new Forbes magazine poll.

Editors ranked talk show titan Oprah Winfrey at number 13 and the Crazy in Love superstar at 17 - making them the only two entertainers to crack the top 20, which German Chancellor Angela Merkel tops, followed by Brazilian President Dilma Rousseff and tech mogul Bill Gates' wife Melinda.

Oscar winner and United Nations Ambassador Jolie, who recently went public with her brave double mastectomy story, comes in at number 37 on the new list, a spot ahead of actress Sofia Vergara, and three places in front of Britain's Queen Elizabeth II at 40.

Other stars who earned mentions include Vogue editor Anna Wintour (41), Lady Gaga (45), Ellen DeGeneres (51) and Shakira (52), while Harry Potter author J.K. Rowling and supermodel Gisele Bundchen scraped in at 93 and 95, respectively.

The power of celebrity had clearly lost its hold on Forbes' annual poll - in 2010, Winfrey was named the third most powerful, while Beyonce appeared at number nine in 2011.
