They are obviously still Crazy In Love for each other and like to be involved in each others' work as much as possible.
So it was wise thinking when Jay-Z asked wife Beyoncé Knowles to perform onstage with him in New York on Saturday.
However, he probably didn't bank on getting so distracted by his wife's leather-clad body that he missed his cue as she performed a couple of songs.
Looking every inch the curvy superstar, mother-of-one Beyoncé, performed her song Diva before Jay-Z joined her for Crazy In Love and Young Forever.
Although crowds were waiting for Jay-Z to come in on the Crazy In Love soundtrack after the rapper, 42, became so distracted watching his wife on the monitors backstage he was heard saying: 'Oh s**t, I should probably rap here.'
And when the song was finished as Beyoncé walked off the stage, Jay-Z gave her playful slap on the derriere.
