All the 34-year-old’s closest friends and family members were there, including aunts Kim and Kyle Richards and their daughters, as well as their Real Housewives Of New York stablemate Bethenny Frankel.

Paris and Nicky’s sister-in-law-to-be Tessa Von Walderdorff — who recently got engaged to their younger brother Barron — was also on hand.

Nicky’s one-year-old daughter Lily Grace — whom she shares with husband financier James Rothschild —  dressed in an adorable pink gown for the event, as she counted down her remaining days as an only child.

Paris matched her in a pink dress of her own — honoring the fact a little girl is en route — while Nicky herself bucked the trend by rocking blue. 

Despite being a girls only affair, Paris’s boyfriend Chris Zylka was also spotted gatecrashing on her Snapchats, but he was likely recruited for his considerable photographic eye.
