"The ladies came out in full tonight!" wrote Jourdan as she shared a photo of the glamorous group on her Instagram. "Thank you beauties for supporting me and @cellforgratitude @karliekloss #AlekWek #Rihanna @caradelevingne @iamnaomicampbell #cellforgratitude."
The 24-year-old host chose a stunning animal print playsuit for the evening, adding some extra glamour by opting for a bright red lip to complete her beauty look.
Meanwhile, Karlie and Cara were the epitome of casual chic: Karlie opted for a simple letterman jacket and dress combo, while Cara showed off her toned figure in a crop top and slouchy trousers.
With New York Fashion Week fully underway, Naomi came to the party after attending the Versus Versace show earlier that day, joined by Rihanna. The pair were spotted laughing together before posing for photographers on the front row, so it came as no surprise that they partied the night away together.
Cell For Gratitude is an initiative set up by Jourdan Dunn, in support of the Sickle Cell Disease Association of America, for whom the stunning model is an ambassador.
