Cardi B knows her worth.

And is apparently banking on the worth of a napkin belonging to Kris Jenner.

The Bodak Yellow rapper hung out with none other than Kim Kardashian and Mama Kris on Saturday night at their Calabasas home.

Cardi let us in on the fun by posting pics and videos to her Instagram which included a tour of the 37-year-old’s home — deemed the “mausoleum” — and a clip of Cardi, Kim, and friends chilling in Kim’s massive closet while holding cut-out faces of themselves, Kris, and Kanye!

The new momma also posted a selfie of herself and the Kardashians, declaring that she was officially part of the “rich people club”!

The 25-year-old — who sported blue hit and a blue tracksuit top — also states that she is selling one of Kris’s napkins on eBay!

We assume she’s joking… but we do know she make money move.
