The queens of self promotion decided to lend a helping hand to their friend!

The Kardashian ladies, minus Kim and Kendall, hit up the Nine Zero One salon launch of celebrity hairstylist Jen Atkin's OUAI hair products last night in Beverly Hills, and they certainly took the opportunity to get decked out for the occasion! Kylie turned it out in a white fur trimmed pencil dress, while Khloe opted for a long coat over some good ol' stripper boots and Kourtney went for a boring black bodysuit.

None of the K sisters brought their significant others, but Kris Jenner did! Boyfriend Corey Gamble threw on a chambray shirt to escort his sugar mama to the bash, and we kinda love how they have matching diamond stud earrings! If you watch Keeping Up with the Kardashians, you know that the momager basically just treats him like a glorified house boy, so we're a little surprised she wanted him to accompany her to the event.

Kimmy K was noticeably absent, but that's probably because she's still trying to shed those pregnancy pounds she gained while knocked up with son Saint. Speaking of whom, when are we gonna get to see a pic of the little guy? He was born in December, and it's now the middle of February! Time for Kimye to come out of hiding and show us America's new royal baby!
