US talkshow host Oprah Winfrey has been declared the world's most powerful celebrity for the second year running in a new survey by Forbes magazine.

The ranking is based on large range of factors including income, internet references, press clippings, broadcast mentions and magazine covers.

Winfrey, 54, topped the list ahead of golfer Tiger Woods and actress Angelina Jolie who were placed second and third respectively.

US singer and some-time actress Beyonce Knowles was fourth and England footballer and La Galaxy star David Beckham completed the top five most powerful celebrities.

The rest of the top ten is made up of a mixture of actors, musicians and authors.

Jolie's partner, Brad Pitt, for example, was declared the tenth most powerful celebrity in the world.

While US rapper and Glastonbury headliner Jay-Z was placed seventh in the list ahead of recently reformed British band the Police.

Forbes declared Harry Potter author Jk Rowling to still be influential despite the wizard series coming to an end; placing her placed ninth in this year's survey.

Her position may in some way be related to the fact she was the biggest earner on the list over the last 12 months.
