Angelenos were treated to a rare performance from Justin Bieber, as he took the stage at SZA and Kendrick Lamar's Grand National Tour yesterday.

Kendrick Lamar and SZA have been sharing the spotlight with each other on their current Grand National Tour, and the “All the Stars” collaborators are bringing their A-list friends into the fold during select shows.

In almost three hours on stage, and the first of three shows at SoFi, Lamar and SZA further established themselves as two of the brightest stars in hip-hop and R&B.
