Justin Bieber took nightclub patrons by excited shock on Saturday night.
The solo artist surprise all those in attendance at 1OAK in West Hollywood, jumping on stage to perform a set of songs at one point late in the evening.
Bieber's brief concert (excerpts from which we've posted below) included the tracks "What Do You Mean," "Sorry," "Where Are U Now," and "Wait For A Minutealong."
They also included a duet with Tyga.
Despite the crowd being filled with people over 21 years old, and Justin's demographic of fans typically being comprised of those in a much younger age group, the performance went over very well.
Which seemed to even take Bieber himself by shock.
"How many people thought you would like Justin Bieber?" he asked the cheering audience a couple songs into his set.
Bieber is all about good deeds these days.
Prior to this unexpected mini concert, he stopped to help a homeless woman in Los Angeles who had fallen down in the street.
As far as we know, moreover, Bieber did NOT pee in any mop buckets during his time at 1OAK. He really has come a long way!
