Episode seven finally brings in Beyoncé's decades-long collaborator, lover, business partner, and homemaker, JAY-Z. "Upgrade U" wasn't one of B'Day's big singles, and yet it marked the duo's official manifesto as a joint powerhouse — as well as Beyoncé coming out of the closet as a rap artist. It might also have been her first foray into drag, something we see about two and a half minutes into the song's music video. Cameos include Betty Wright, Destiny's Child, and lots & lots of HOV.
