To close the MTV Europe Music Awards on Saturday, host Selena Gomez introduced Queen with a mystery singer who, halfway through The Show Must Go On, was revealed to be Adam Lambert.
Lambert cites Freddie Mercury as his favourite singer.
At the MTV Europe Music Awards, held in Belfast, Lambert performed an eight minute melody featuring The Show Must Go On, We Will Rock You and We Are The Champions.
The MTV Europe Awards awarded Queen the Global Icon Awards earlier in the night at the event.
Adam tweeted after the show “What an enormous honor to sing w QUEEN! I could feel the spirit of Mercury alive on stage tonight! Thank u Brian and Roger and crew. LOVE”
