We knew the announcement was coming.  Now Queen and Adam Lambert have confirmed they're hitting the road together for a North American tour.

Lamberthas performed with the legendary British rock group on a number of occasions, both in the U.S. and overseas, but he and Queen have never actually toured in the U.S.  That changes beginning June 19 at Chicago's United Center, the first of 19 dates in all in the U.S. and Canada, wrapping July 20 at the Merriweather Post Pavilion in Washington, D.C.

When he performs with Queen, Lambert stands in for the band's founding lead singer, Freddie Mercury, who died in 1991 of AIDS-related illness.  They first joined forces in 2009 for a performance of "We Are the Champions" on American Idol.  In the summer of 2012, Queen + Adam Lambert performed six shows in Europe, and this past fall, they also performed at a multi-artist show in Las Vegas.

"I'm honored to be able to pay my respects to Freddie's memory," Lambert said in a statement.  "He's a personal hero of mine, and I am deeply grateful for the chance to sing such powerful music for fans of this legendary band."  Queen guitarist Brian May kept his comment succinct: ""Let's ROCK those beautiful arenas JUST ONE MORE TIME!”

Tickets for Queen + Adam Lambert go on sale Friday, March 14 via the Live Nation mobile app and at Livenation.com.  American Express Card Members get early access beginning Monday, March 10 in the U.S., and Tuesday, March 11 in Canada.
