Beyoncé brought out the old and the new Saturday night ... unveiling her new 'Renaissance' flick, and bringing together the group that launched her career. 

Bey hosted the debut of her film at the Samuel Goldwyn Theater in Bev Hills, and Destiny's Child was front and center. Kelly Rowland and Michelle Williams showed up, along with founding members of the group, LaToya Luckett and LaTavia Robertson.
