Former “American Idol” contestant Adam Lambert will join legendary British rock band Queen this summer for a 19-date North American tour, which kicks off June 19 at Chicago’s United Center and wraps July 20 at the Merriweather Post Pavilion in Washington, D.C.

Lambert and original Queen members Brian May and Roger Taylor made the announcement Thursday during an appearance on “Good Morning America.”

“Queen is one of the quintessential rock bands of all time…they’ve influenced bands for years to come,” Lambert said on “GMA.”

Lambert has appeared with May and Taylor at numerous shows in the past, but this will mark his first official tour with the group. Their first collaboration was a performance of “We Are the Champions” during the season eight finale of “Idol” in 2009. Lambert was named runner-up and has since released two solo albums.

The trio teamed up once again in 2011 to perform “The Show Must Go On,” “We Will Rock You” and “We Are the Champions” at the MTV European Music Awards in Belfast and Lambert joined the band during the summer of 2012 as they performed across Europe.

In a press conference held Thursday at Madison Square Garden, May said, “This happened organically with Adam. 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.”

Lambert also described filling in for original Queen frontman Freddie Mercury, who died in 1991 of complications from AIDS, as “daunting” but added “It’s such a treat to get onstage, pay my respects and sing some of the greatest songs ever written.”

The tour will bring to trio to several major cities including New York, Los Angeles, Dallas, Vancouver, Montreal and Las Vegas. Tickets will be available March 14 through Live Nation’s website and mobile app.
