The Rolling Stones partied with Lady Gaga until 3am after their gig on Saturday night. The veteran rockers - made up of Sir Mick Jagger, Ronnie Wood, Charlie Watts and Keith Richards - and the 'Born This Way' hitmaker enjoyed a "relaxed" affair at The Carlyle Hotel, New York City, with 150 others following their collaboration at the Prudential Center in Newark, New Jersey. An insider told the New York Daily News newspaper: "The party went from around midnight to almost 3am. They really just hung out, relaxed and all chatted with each other." Earlier in the evening, Gaga performed a rendition of 'Gimme Shelter' with the 'Brown Sugar' hitmakers for their final '50 and Counting' show, which also saw them take to the stage with Bruce Springsteen and The Black Keys, to celebrate their 50th year of rock 'n' roll. The Rolling Stones performed a 22-song set at the gig, including their 1978 hit 'Respectable' with John Mayer, and their former bandmate Mick Taylor also made an appearance.
