The always stunning Beyonce let loose at her sister Solange's New York Fashion Week party earlier this week.  The pair of sister and everyone else in attendance appeared to be having a great time as numerous photos were taken of everybody dancing and enjoying some pleasant drinks.  

Beyonce was even photographed popping a champagne bottle and hitting the dance floor with a freshly poured glass of some expensive bubbly.  She wore a sexy two piece outfit along with a white coat, and sported a fresh new braided hair style which really allowed her gorgeous face to shine.  Meanwhile, Solange partied it up in a pink outfit consisting of comfortable pants and a blazer top with no shirt underneath.
