Beyoncé and Jay Z Dressed Up as Barbie and Ken—See the Pics

You wouldn't expect Beyoncé to make an appearance at a Halloween party in just any old costume, would you? True to form, the singer blew everyone out of the water with her getup last night. She donned a coordinated couples costume with Jay Z: Barbie and Ken dolls, complete with the plastic boxes and everything.

Beyoncé went for a '50s-inspired look, wearing a striped one-piece swimsuit and Sunday Somewhere's Pixie Sunglasses ($290), while Jay Z went for a black-tie tuxedo outfit. The pièce de résistance? In one photo, daughter Blue Ivy looked on wearing a leather jacket with "Barbie" inscribed on the back. How's that for the ultimate group costume? Not that we had any doubts, but this super-cute trio officially won Halloween. We can't wait to see what they come up with next year—something tells us it will be even better.
