Beyoncé and Jay Z partied it up in NYC on Halloween [1] night, and they threw it back all the way to the '80s with their awesome costumes. The musical power couple channeled Eddie Murphy [2]'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 [3] gave us a dose of Who Framed Roger Rabbit with a dead-on Jessica Rabbit costume [4], and Jessica Alba [5] tapped into the '90s with her Romy and Michele's High School Reunion-inspired look [6]. Keep reading for another look at Bey and Jay's costumes, and then check out our entire 2015 Halloween costume roundup [7].
