Beyoncé and Jay Z partied it up in NYC on Halloween night, and they threw it back all the way to the '80s with their awesome costumes. The musical power couple channeled Eddie Murphy's Coming to America for their looks, serving it up as Prince Akeem and Queen Aoleon. But that's not the best part! A couple snaps from Beyoncé shows that even Blue Ivy got in on the fun as a very adorable Imani Izzi! The Knowles-Carter family's getups aren't the only throwback costumes we saw this year — Heidi Klum gave us a dose of Who Framed Roger Rabbit with a dead-on Jessica Rabbit costume, and Jessica Alba tapped into the '90s with her Romy and Michele's High School Reunion-inspired look.
