The "KUWTK" star and her family rang in the singer's 28th bday at Cinepolis Luxury Cinemas in Thousand Oaks — just in time to watch the "Avengers" movie!
Kim, Kourtney, Khloé, Kris, Kanye West and Corey Gamble were all at the "Avengers" party to help Scott celebrate his big day ahead of time, where they rented out a private theater and watched the Marvel movie. Kylie even gifted Travis a cake that stayed on-theme, featuring her, her baby daddy and Stormi.
The family of three brought the cake to life, posing in the driveway in full costume earlier in the day. Sharing several pictures from their photo opt, Kylie dressed as Captain Marvel while Travis wore an Iron Man suit. They even got Stormi in on the superhero action.
Travis actually turns 28 on Tuesday, so this was just a warm-up party!
