Kiss and Queen (featuring Adam Lambert on vocals) will headline separate nights of the 2012 Sonisphere Festival in England this summer. This news seemingly ends weeks of speculation as to whether or not Lambert would be joining Queen in some capacity.

The three night festival kicks off Friday, July 6 at Knebworth Park with a bill topped by a “European exclusive” headlining performance by Kiss, who are preparing to release their 20th studio album ‘Monster’ sometime in 2012.

Queen and their new ‘American Idol’-bred buddy will highlight the festivities the next night (Saturday, July 7), with help from the Darkness and Ghost among others. Faith No More will head up the third and final night on Sunday (July 8). Color all us stateside rock fans extremely jealous!

If you have the means and the rock madness for such travel, tickets go on sale this Thursday (Feb. 23). You can get the full lineup and other information at the festival’s official website.
