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.

Another post featured a series of snaps of the immaculately planned pink extravaganza, which was designed by Mindy Weiss, the LA-based party planner who also designed the enormous Stormi World party thrown for Kylie's daughter's first birthday.

'Another magical Kylie Party brought to life by @mindyweiss & team,' she captioned the photos. 'Thank you for always bringing my visions to life so beautifully. Last night was SO MUCH FUN! Omg the best night with the best people. Thank you God so so blessed.'

Though much of the party was painted pink, the photos revealed that the interior was done up in shades of peach and lavender before being bathed in pink light.

In addition to photos of the stylized bathroom and its retro bathtub, she showed off the '50's-chic tables and artistically arrayed displays of her skin products.

The event featured a rink for guests to rollerskate in, and one wall was covered in dozens of hanging pink skates.

After posting videos of ramen in Kylie Skin containers, she showcased another transformed Japanese cuisine, intricate sushi featuring purple rice.

The event also featured pizza, french fries doused in melted cheese and pink cupcakes.

The space featured diner-style booths for guests, which were decorated with steamy portraits of the host.
