Kylie Jenner -- I Need to Start Dating A$AP

Kylie Jenner was flying solo Friday night -- no Tyga in sight -- but she may not have left solo.

The freshly-single 18-year-old partied at Hyde on the Sunset Strip in WeHo until 2 AM. Apparently Justin Bieber was inside and so was A$AP Rocky.

Justin stuck to his theme of giving impromptu performances by jumping on a table inside the club to perform "What do you mean?".
