The 'For Your Entertainment' singer stopped to chat with fans and sign autographs just before an appearance on Good Morning America on Thursday, 6 March, where he joined original Queen members Brian May and Roger Taylor to announce they'll embark on a 19-date tour of North America from June.
"Queen is one of the quintessential rock bands of all time," said Adam. "They've formed music no one has ever heard before and influenced bands for years to come. To be able to bring these songs to life on stage…"
Roger returned the compliment, saying: "We feel Adam is one of the few singers that can actually deliver our songs."
We have to say, having watched Adam + Queen in concert in London back in 2012, we totally agree. What an amazing show!
And who can forget that incredible performance at the MTV Europe Music Awards 2011 in Belfast, Northern Ireland, where Adam belted out Queen classics including 'The Show Must Go On' and 'We Are The Champions'.
American Idol fans will also remember Queen joining Adam on the finale of the reality show back in 2009 for a rendition of 'We Are The Champions'. Adam finished runner-up to Kris Allen - proving alongside acts like One Direction, JLS, Olly Murs and Jennifer Hudson that winning one of these shows isn't everything.
"I'm completely in awe of the Queen phenomenon. The thought of sharing the stage for a full set in North America is so beautifully surreal," said Adam.
Adam continued: "I'm honoured to be able to pay my respects to Freddie [Mercury]'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 this tour will be a huge milestone for me, and with the support of Brian, Roger and the rest of the band, I feel like magic will be on display."
Sadly, the tour is just in North America for now. If you happen to be planning a visit to the States through June or July this year, then you can get tour dates and tickets via LiveNation from 14 March.
If you're not, then let's all keep our fingers crossed they also decide to visit our shores!
