The soon-to-be father left his GF at home while he performed at LIV nightclub in Miami on Sunday night.
While Kylie reportedly decided to sit this one out (a nightclub is no place for an expectant mother), the beauty boss' crew were spotted at the club watching their friend's baby Daddy perform.
Kylie's friends, Justine Skye and Anastasia Karanikolaou, were spotted dancing in the crowd, along with Kendall's bestie Hailey Baldwin.
Partygoers told TMZ that all three girls, and the groups they were with, "ended up in the DJ booth together at one point in the night -- where Travis raged a bit himself though his set".
Poor Kylie missed out on all the fun!
