As previously reported
, there have been talks about Adam Lambert possibly joining British rock band Queen in a performance which was previously clarified by the American Idol alum, tweeting, "I haven't confirmed any guest appearances."
After weeks of neither confirming nor denying rumors, he finally confirmed the news via Twitter.
As many suspected, I can finally confirm: I have been invited by Queen to sing one very special concert! Sonisphere at Knebworth July 7th!
He added, "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!"
Adam has previously performed with Queen members Brian May and Roger Taylor last November.
