[Watch] Kendrick Lamar and Best Coast's Bethany Cosantino Perform "No Make-Up (Her Vice)"

During his performance in Portland on Wednesday night, Kendrick Lamar was joined onstage by a rather unlikely guest. Providing the chorus vocals on the song "No Make-Up (Her Vice)," originally sung by Colin Munroe and featured on last year's Section.80, was Best Coast's Bethany Cosantino. This was the first time Lamar has performed the song in a live setting, and the combination of him and Cosantino was surprisingly good. Watch the replay above.
