Lady Gaga joins Adam Lambert and Queen on the Australian leg of her tour...

Whilst on the Australian leg of her ArtRave tour Lady Gaga joined Adam Lambert and Queen to delight the audience in Sydney.

Together the pair sang, Another One Bites The Dust, afterwards Gaga took to Instagram to write, '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,'

“So much fun tonight! @ladygaga” Lambert wrote on his page.

We love that Blazer on Adam Lambert... Must get one.
