Taking to Instagram, the mum-of-three announced her sisterly night out with a made-up selfie, captioning ‘Hot date with @kyliejenner tonight’.
And a hot date it definitely was.
The 18-year-old looked every inch the stunning superstar in a sparkling full-length two piece, made up of a full floor-sweeping maxi skirt and bedazzled crop top.
Now that’s a princess gown if ever we’ve seen one.
The beauty entrepreneur didn’t skimp on the make-up either, rocking a beautifully bronzed look. Her raven hair was pulled back into a tight top knot, making her glam all the more dramatic.
Kourtney Kardashian also stood out in a gorgeous Julian Macdonald bustier dress, paired with her signature red lip.
The pair arrived to a swarm of cameras at the at the InStyle And Warner Bros bash, hosted at the The Beverly Hilton Hotel.
Kylie has had a bit of a tough time lately, after fresh cheating rumours surfaced about her boyfriend Tyga and a Brazilian model, so we’re sure she was in need of some girl time.
You’ve bounced back beautifully, KJ.
