Jack White thinks Britney Spears is "more authentic" than legendary rockers.

The Dead Weather guitarist believes the 'If U Seek Amy' hitmaker is more genuine than some of the world's most respected rock stars, including Bob Dylan, because she doesn't pretend to be anything other than a pop singer.

He said: "I don't know if Bob Dylan and Tom Waits are as authentic as I think they are. Perhaps they're not. Sometimes you start thinking that maybe Britney Spears or someone like that who's doing exactly what they want to do in the way that they best know how, is more authentic than any of those people you could mention."

The 34-year-old guitarist - who was speaking at a guest lecture at Dublin's Trinity College on Sunday night (18.10.09) - also revealed he had an "incredible" time working on electric guitar documentary film 'It Might Get Loud' with Led Zeppelin's Jimmy Page and U2's The Edge.

He told the audience: "It was a pretty incredible experience to work with those two guys."
