Queen's Brian May has said that he believes fans will be happy with Adam Lambert fronting he band.
The singer will join Brian May and Rodger Taylor for their headline slot at this year's Sonisphere festival.
In a statement May added that Queen's former frontman Freddie Mercury would approve of Lambert.
"Judging by my incoming mail, this decision will make a lot of people very happy. 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."
Lambert added that he hoped to "pay respects to Freddie's memory'':
I'm completely in awe of the Queen phenomenon. The thought of sharing the stage for a full set is so beautifully surreal. I'm honoured 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."
Kiss will headline the opening night of the festival (July 6), followed by Queen on the Saturday night (7), with Faith No More closing Sonisphere on the Sunday (8).
The festival takes place at Knebworth Park will also feature performances from Evanescence, Incubus, The Darkness, Mastodon, Mariyln Manson, Refused, I Killed The Prom Queen and The Blackout.
