After what seems like countless rounds on the rumor mill — and just as many denials — the worst-kept secret in pop music has finally been officially confirmed: Adam Lambert will perform with Queen this year.

“As many suspected, I can finally confirm: I have been invited by Queen to sing one very special concert!” tweeted Lambert. And he wasn’t kidding about that “special concert” part, either — he went on to reveal the location and date: “Sonisphere at Knebworth July 7th!”

“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,” Lambert added. “Gonna be a surreal night!”

“Judging by my incoming mail, this decision will make a lot of people very happy,” said Queen guitarist Brian May in a press release. “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.”

“I’m completely in awe of the Queen phenomenon. The thought of sharing the stage for a full set is so beautifully surreal,” added Lambert. “I’m honored to be able to pay my respects to Freddie’s memory. 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. I know the evening will be a huge milestone for me, and with the support of Brian, Roger and the rest of the band I know magic will be on display.”
