Queen fans were in for a treat as Lady Gaga joined the rock band for their concert in Australia.
Lady G rocked up to the gig sporting a big curly black wig and her usual daring attire. The pop diva rocked out on stage with the musical legends alongside the band?s new singer Adam Lambert.
It seems it was a dream come true for the 28 year-old as the hit-maker took to Twitter after the show to write that she had just performed with Queen and now she was the ?happiest girl alive?.
