Justin Bieber kicked off his L.A. takeover with a few surprise guests.

The "Company" singer brought out Big Sean and Chance The Rapper to perform on the first of his three gigs at the Staples Center.

Big Sean went onstage to deliver his verse during "No Pressure" - but stayed backstage for "As Long As You Love Me", sadly - while Bieber added "Confident" to the setlist for the night since Chance was in attendance.

It's safe to say the crowd (which included Kourtney Kardashian) went wild for all three artists.

Check the performances out down below.

Let's hope he keeps "Confident" on the list from now on.
