Adam Lambert's tour with Queen has been receiving rave reviews in its worldwide tour, but the Wednesday night crowd in Sydney got a bonus surprise: Lambert was joined on stage by Lady Gaga for a guest duet of "Another One Bites The Dust", which they tore into with delighted abandon to a thrilled audience.
Wrote Gaga on Instagram: "Tonight I felt alive in a way I have not before. I returned to the Radio GaGa mothership to pay homage to my leaders. It was emotional and wild."
Added Lambert, with the top photo: So much fun tonight! @ladygaga
If you weren't able to be in Australia last night, you can watch a fan's video of the performance AFTER THE JUMP…
