Beyoncé wore a black and white striped Alice + Olivia coat -- which perfectly matched Jay's own striped T-shirt -- over a mesh and lace floral Marco de Vincenzo dress, while Blue donned bunny ears and a giant fur coat.

The Carters stepped out to celebrate the Obamas last Easter in office, where Blue also got to meet Elmo and other Sesame Street characters in person and join the egg hunt.

Oh, and Blue Ivy with her little basket is officially the cutest Easter bunny ever.
