Adam Lambert on teaming up with Queen: 'I'm having so much fun'

Adam Lambert says he is having "so much fun" as Queen prepare to head out on tour.

The band are due to open their North America run tonight (June 19) in Chicago and the group, who Lambert is fronting, will then play Asia and Australia.

The singer told Rolling Stone that he has been enjoying time with Brits as the rockers gear up for life on the road.

Referring to how Queen added some extra dates due to huge demand, Lambert said: "Additional shows are kind of up to the band. They keep saying with a smirk and an eyebrow-raise, 'We want to get out one last time'. I think additional shows could happen. I'm definitely down. I'm having so much fun."

Speaking meanwhile about the filling the shoes of the late Freddie Mercury, the 'Trespassing' man said:

"It's not an easy feat. I think a lot of the apprehension has faded because we've done this a number of times in the past couple of years. That's not to suggest I'm getting cocky at all, because I will never compare to Freddie Mercury. He's one in a million. At this point, I know how to strike a balance between honouring the way these songs were originally meant to be sung and my own instincts, my own choices."
