The finale of America’s Got Talent got an injection of star power from the worlds of pop, R&B and hip-hop. Justin Bieber headlined a strong contingent of performers that included G.O.O.D. Music MC Big Sean and R&B veteran Ne-Yo.

Following an introduction by host Nick Cannon, Bieber—wearing a silver jacket and black leather pants—took to the stage with a small army of back-up dancers and a confident Sean for their single “As Long As You Love Me.”

It’s the latest track from the pop superstar’s near platinum album Believe. And judging by the enthusiastic screams from Bieber’s mostly female fans in the audience, witnessing the Canadian teen sensation sing, dance, and rap with his Detroit rhyme collaborator was a television win.

The song is from his upcoming Motown album R.E.D., which is due out in stores November 13. Check out the performance here
