The Weeknd Joined Travi$ Scott Onstage In Houston

Travi$ Scott is currently supporting The Weeknd on his Madness tour, and the singer made a cameo last night to help perform "Antidote," Scott's surprise hit (it reached No. 4 on the last week's R&B/Hip-Hop Airplay chart). This isn't their first time collaborating; The Weeknd also appeared on the MC's Rodeo album—see "Pray 4 Love."

The two artists will have plenty of opportunities to play together next year, since both are heading out to support Rihanna on tour in 2016. Revisit Scott's FADER cover story.
