Lady Gaga and Beyonce have made it on to Forbes' list of the world's 100 most powerful women.

The Poker Face hitmaker was number seven in 2010, but has fallen to number 11 - although she still managed to beat TV titan Oprah Winfrey, who sits at number 14.

Lady Gaga is the leading celebrity in the politician and businesswoman-heavy countdown - Beyonce is the next big star at number 18.

Angelina Jolie is at 29 thanks to her humanitarian work and supermodel Gisele Bundchen is at 60, one ahead of Harry Potter author J.K. Rowling.

Top of the countdown is Germany's chancellor Angela Merkel, while Secretary of State Hillary Clinton is second.
