Helping James Corden celebrate his 50th edition of The Late Late Show, Adam Lambert took to the stage to sing a special edition of Queen's 'We Are The Champions' in tribute to the show's host.
Lyrics included: "He is James Corden, my friends, and he'll host 'Late Late Show' 'til the end.", and James even joined Adam on-stage for an encore.
Later on in the episode, Adam returned to perform his single 'Ghost Town' to rapturous applause.
Adam's latest album 'The Original High' was released last month, becoming his highest-charting in the UK to-date and his third consecutive top three record in the US.
