The brief clip showed the Kardashian–Jenner clan, minus Kylie's sister Kendall, as they lounged about in an all-pink bathroom.

The set was filled with floating soap bubbles, and Kylie reclined seductively in the bath tub. 

Kylie was dressed in the same pale pink strapless mini-dress with peekaboo sides that she wore earlier in the evening. 

Khloé played with her long hair and Kourtney pretended to chat on the phone in the playful photo set. 

As the camera panned, it showed Kim struggling to hold herself up on the fluffy pink stool.

The Keeping Up With The Kardashians star also shared a number of photos to Instagram of herself posing with guests.

She cozied up to Caitlyn Jenner in one photo, and showed her mother Kris Jenner in a separate solo shot. Both parents were dressed in matching hot pink outfits.

Kylie also posted pictures with popular makeup YouTubers, including makeup artist Nikita Dragun and CoverGirl ambassador James Charles.

While posing with Kris' boyfriend Corey Gamble, the reality star appeared to lose her concentration and spilled a bit of her drink.
