Adam Lambert has a date with rock royalty.
The former American Idol singer is about to pay tribute (again) to one of his, well, idols, by serving as frontman for the legendary band Queen this summer.
The U.K. gig, which will find Lambert filling the shoes of the late, great Freddie Mercury, is for one night only, though.
"As many suspected, I can finally confirm: I have been invited by Queen to sing one very special concert! Sonisphere at Knebworth July 7th!" Lambert tweeted on Monday, adding: "Sorry to be coy about the details the past few weeks, but I made a promise to keep it under wraps as best I could. Gonna be a surreal night!"
The band's Brian May and Roger Taylor also confirmed Lambert's participation when Queen takes the stage at the rock festival, which also served as the setting for the group's final concert with Mercury in August 1986. The beloved rock star died in 1991.
"Judging by my incoming mail, this decision will make a lot of people very happy," May wrote on the Sonisphere Festival 2012 website regarding Lambert. "It's a worthy challenge for us, and I'm sure Adam would meet with Freddie's approval! And what better place to revisit, and walk those emotional paths than Knebworth? It will be a rush."
Of course, this isn't exactly unchartered territory for Lambert. He not only belted out "We Are the Champions" with Queen on the Idol finale in 2009, but also joined them for a performance at the MTV Europe Awards last November.
