Beyonce and Jay Z won Halloween on Monday night when they dressed up as black Barbie and Ken. Queen Bey took to Instagram to share photos of her and her husband in “Black Barbie” boxes. The singer wore a furry pink coat and leotard with a high ponytail and heels, while the rapper rocked a tux and a silver bowtie. Meanwhile, Blue Ivy wore a jacket emblazoned with the word Barbie. Fans were quick to applaud the family for their coordinated efforts, and to express disbelief over Jay Z agreeing to spend the evening inside a Barbie box “Jay Z is really just happy to be included in everything Beyoncé does. Ladies, that’s how we need to train our men,” one observed.
