Beyonce does Barbie! Singer and Jay Z sport doll costumes for Halloween

Updated: 

Never let it be said that Beyonce does things by halves.

The superstar singer and her husband Jay Z - and their adorable little girl Blue Ivy - went all-out with their Halloween costumes, dressing themselves as vintage Barbie dolls.

Beyonce, obviously, led the charge in her figure-enhancing black and white-striped bodysuit and black wig as she posed inside a box that read "Black Barbie".

She also covered up in another Instagram shot in a pink fluffy coat, naturally.

And although she looked sensational in terms of her costume, it was the Halo singer's posing that really nailed the brief.

Next to her was the rapper, as a "Black Collector Edition" of the Ken doll, clad in a tuxedo and in a box of his own.

Blue Ivy, four, looked as cute as a button in her little rockstar-inspired doll look, complete with a tutu and leather jacket. Fierce.

Earlier over the Halloween weekend, Beyonce and Blue Ivy had dressed up as 90s music icons Salt-N-Pepa.

Jay Z dressed as Dwayne Wayne from The Cosby Show spin-off A Different World, and even Beyonce's mum Tina got in on the action as Salt-N-Pepa's DJ Spinderella.
