The Biebs is having an interesting holiday weekend.
Justin Bieber, 22, was spotted partying it up with Kourtney Kardashian, 37, at Story Nightclub in Miami on Sunday night for the singer's Purpose World Tour after-party.

The reality star was in town with her three children and ex-beau Scott Disick.
Reports say Bieber disappeared around 1 a.m. and returned to the DJ booth with Kardashian. Kardashian was at the club for owner David Grutman's birthday.
A source told People that Bieber "went right down to her table and brought her up to a private table behind the DJ booth" at one point during the night.
Just two days later, Bieber took to Facebook to question the meaning of life. We're not sure the two situations are related, but we're loving this existential Biebs.
What is your purpose, Justin? Maybe it's to be with Kourtney Kardashian. Maybe it's to dye your hair purple.
We'll just wait here while you figure it out.
