Always one to attempt to outdo herself, it’s possible Kylie Jenner had the best weekend ever. Seemingly unfazed by her rumored break-up with Tyga, not only did she crash a prom, the youngest Jenner partied hard in particularly out-of-this-world fashion.

HBD @simihaze! Thanks for spending it with us last night. 🔫 #ThePeppermintClub

A blonde and bobbed Jenner attended her friends’, twins Simi and Haze, birthday party, converting Los Angeles’ exclusive The Peppermint Club into an otherworldly stage for the evening. The celebration, touted a “Galactic Rodeo,” brought together a bevy of Hollywood starlets including Charli XCX, Jordyn Woods, Justine Skye, and Hailey Baldwin, alongside a requisite, and much-appreciated, flood of social media documentation, Jenner debuted her “inner space cowgirl,“ which means she wore a silver cowboy hat and metallic bandana. And ate tacos.

my inner space cowgirl came alive last night ..

Her pals took the theme even further: Blue-haired Hailey Baldwin went “battle star gyalactica,” posing with a bedazzled Justine Skye.

A proper night out is nothing without an after-party, obviously. The girls capped their evening with a dip in the pool.

After party 😛😛😛😛
