Wearing a plunging copper patterned long-sleeved mini dress and tan over-the-knee suede spike heeled boots, the leggy blonde bombshell and company were seated at a dance floor banquette table where they enjoyed Belvedere vodka cocktails, from bottles specially inscribed for the birthday girl, Patron and Champagne. The tight-knit bunch was seen dancing to classic and contemporary music from multiple genres.

Hadid was later surprised and delighted when presented with a gorgeous custom multi-level birthday cake topped with a giant faux martini and the number “21”. Hadid’s celebration continued until the wee hours with the ebullient beauty soaking in every bit of the memorable and monumental event.
