Lady Ga Ga made her return to the stage last week after having surgery on her hip. The Bad Romance hitmaker had been suffering from synovitis, a severe inflammation of the joints, and was forced to cancel part of her Born This Way Ball tour earlier this year as a result. After recently ditching her gold-plated wheelchair, she gave an impromptu performance with jazz singer Brian Newman at the Rose Bar in Gramercy Park Hotel, New York City last Thursday (May 9). Lady G is said to have performed tune Watch Over Me with Newman and his band. Newman later tweeted: "Thanks to the 1&only @ladygaga for coming out to @GPHhotel tonight an singing a song!! @tommylondon @angiepontani @mrmartye @thedirtypearls." Another Twitter user, Alex Smith, later added that Gaga "really made the ‪@BrianNewmanNY‬ band's night!"MTV
