"5am birthday adventures with my two fav people," Kylie wrote on Insta.
A source later told E! that after opting out of the spotlight for a few years - having suffered serious social anxiety - Rob was hanging out with Kendall and Kylie's friends at his little sister's bday.
The insider said: "He seemed relaxed and was trying to ease himself back into social settings. He looked really happy to be out and about with his sisters."
