GaGa 'most influential artist of 2010'

Lady GaGa has been named the world's most influential artist in Time magazine's Time 100 list of the most influential figures alive today.

The singer clinched the top spot in the list of 25 stars, with Conan O'Brien coming second and Kathryn Bigelow and Oprah Winfrey coming third and fourth.

GaGa's entry featured a tribute from veteran popstar Cyndi Lauper, who described the 'Poker Face' singer's lyrics as "incredibly literary" and "sophisticated".

Lauper wrote: "When I see someone like GaGa, I sit back in admiration... She isn't a pop act, she is a performance artist. She herself is the art."

The top ten also featured Robert Pattinson at number six and Taylor Swift at nine. Meanwhile, Glee star Lea Michele was a surprise entry at number 13, above established stars such as Simon Cowell and Sir Elton John.
