The famous entrepreneur hosted a huge star-studded bash for her 44th birthday on Saturday night at her mansion in Beverly Hills.

The pad was covered from head-to-toe in pink decor including giant balloons, flowers, and #sliv signage ... if ya don't know, "sliving" is a term coined by Paris combining "slaying" and "living."

Guests arrived to a long pink carpet which led into a massive room decked out with more pink EVERYWHERE including big hearts with "PARIS" written in them.

The icon shared tons of footage from inside the celebration ... including video of her and a friend dancing on a table to her best friend, Britney Spears' song, "Work Bitch."
