"I had a life dream to be transported in a time machine to 1973 NJ, beer + badboys. Someone heal me it happened + then I sang with the Stones," she Tweeted after the performance. Clad in a Ray Brown jumpsuit, which made Gaga feel "like a star," the Born This Way hitmaker strutted all over the stage as she and Mick Jagger delivered a dynamic duet.
