Gaga was there to showcase her duet with the band, Sweet Sounds of Heaven, from the album.

She also tried to give Mick a run for his money as she busted some moves on stage while belting out the new hit. 

Mick matched her energy and showed off his signature moves as the duo harmonized together in front of the star-studded crowd.

Gaga commanded attention for her surprise cameo. The songstress dazzled in a red and black sequined jumpsuit with flared legs and a plunging neckline.

She finished the look with a pair of black platform shoes.

Mick, meanwhile, had on a checked jacket, which he took off mid-performance.

The late Tina Turner previously revealed in an interview with Daily Mail that Mick learned to dance from his mother.

She said: ‘Mick wanted to dance – and I was a dancer – but he never gave me the credit! He said his mother taught him how to dance. But we worked with him in the dressing room, me and the girls, and we taught him how to Pony.’
