Things got emotional at the Billboard Music Awards Sunday night.

Wiz Khalifa performed his No. 1 song “See You Again” alongside Charlie Puth and violinist Lindsey Stirling at the award show. The song, which has dominated the Hot 100 Billboard chart for the past five weeks, was featured on the “Furious 7″ soundtrack.

Khalifa’s song plays in the final moments of the film as a moving tribute to Paul Walker and his character Brian O’Connor. Director James Wan has said that he’s cried every time he watched the ending with the song.

Clad in a maroon suit, Puth took to the piano and crooned out the hook to the moving ballad. A passionate Khalifa bounced energetically around the stage in between rapping his verses, while Stirling played the violin in a glittering gold gown.
