Rolling Stones joined by Lady Gaga and Bruce Springsteen during final concert

The Rolling Stones celebrated the final concert in their reunion tour in style on Dec. 15. Performers including Lady Gaga, Bruce Springsteen, John Mayer and The Black Keys joined the rock band during their Newark, N.J. show.

The "50 and Counting" Rolling Stones tour wound to a close over the weekend after hitting cities like London and New York City. Gaga performed "Gimme Shelter" along with the Stones, while The Black Keys sang "Who Do You Love" and Mayer and Gary Clark, Jr. collaborated on "Goin' Down." Springsteen performed "Tumbling Dice" with the band.

While some of the Mother Monster's dance moves are questionable in this video, its clear that everyone's heart was in the right place. It seems like this concert was one that does the Stones' legacy justice. Mick Jagger also gave a shout out to those affected by the tragic shooting in Newtown, Conn.
