LAS VEGAS, NV - SEPTEMBER 20: Singer Adam Lambert performs with Queen during the iHeartRadio Music Festival at the MGM Grand
Ethan Miller

Adam Lambert is joining Queen's summer tour, the rockers revealed at a press conference at Madison Square Garden this morning. The 19-date arena trek begins at June 19 at Chicago's United Center on July 20. And as any Glambert will tell you, this cross-generational musical partnership has been a long time in the making.

As a hopeful American Idol contestant in 2009, Lambert busted out "We Are the Champions" with remaining members Brian May and Roger Taylor at the show's season finale. They continued to tease a formal musical relationship with Lambert fronting a performance of Queen's biggest hits at the 2011 MTV EMA Awards, a handful of European shows in 2012 and then an electrifying performance at the 2013 iHeartRadio Music Festival

This new tour will be their lengthiest time together. Finally!

"Adam is the most incredible frontman," Taylor said at the press conference. "He's a great diva, and I mean that in the best possible way. We need that theatrically."

May added that, "People are going to ask whether it's Queen without Freddie. I don't know. We just want to go out there one more time. Adam isn't an imitator. We're going into new territory."

Meanwhile, Lambert is excited to pay homage to band's late frontman, Freddie Mercury. "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."
