The 'Lemonade' singer gathered her nearest and dearest for a party of epic proportions in NYC, where the dancing was hot, the flares were big and the hair was bigger. As with all good parties, the soiree was documented by its very star-studded guest list, including her fellow Destiny's Child Michelle Williams.
Williams and her stylist Diandre Tristan rocked up to the star-studded bash as 'I Got You Babe' chart-toppers Sonny & Cher. Williams posted onto Instagram:
"Good times with @diandre_tristan at Queen B's birthday party. Can't half step when it's a themed party. @diandre_tristan was @gucci'd down!!! I called him with an idea and he made sure my look was right. Custom jumpsuit by @iluvtylerwells! Makeup by @elenageorge1mkp. #sonnyandcher #michellewilliams #balance"
The outfit was undoubtedly inspired by the one that Cher wore at the 1975 Rock Music Awards:
