Yes, Serena appears in Beyoncé's latest work. Her visual album Lemonade is a 52-minute cinematic experience that includes among its 12 tracks a song called "Sorry." That features none other than Serena—with Beyoncé perched on what appears to be Serena's throne from her SI Sportsperson of the Year shoot.
It quickly becomes obvious that all of Serena's recent dance action, from taking group lessons to educating others, was for startlingly good reason. She drops low, writhes around and plays to the camera like the ultra-confident queens of culture that ReRe and Bey are.
Earlier in the evening, Serena actually alluded to potential involvement with the Lemonade project on Instagram in a photo post that featured her sporting (what else?) a bedazzled face.
