Last night in Los Angeles, Travis Scott hosted his .WAV party in celebration of his new Beats 1 radio show of the same name, but the most notable part of the evening was when Scott debuted the official remix of Desiigner's "Timmy Turner," which features rapping from Kanye West.

The track appeared to have been played off of somebody's phone; Perhaps Kanye's, who was in attendance and on stage as the song played. Desiigner wasn't present, but Scott called him on FaceTime and Desiigner rapped along as Scott held the mic up to his phone. Scott also premiered new music videos for his songs "Pick Up the Phone" and "90210" during the event.

Check out footage of the "Timmy Turner" remix debut below (and talk about it in our forums).
