The secret to Beyoncé and Jay Z's everlasting love? These matching power suits, probably

Over the past 14 years of Beyoncé and Jay Z's relationship, many have wondered what the secret behind their long-lasting success is.

Well, now we know: Matching grey power suits!

Such was the aesthetic they went with for Monday night's premiere of Hands of Stone. The movie stars Usher, who blessed his Snapchat followers with a picture of the couple in their relationship goals uniforms.

In retrospect, it is not surprising that Beyoncé would turn to matching outfits as a way to strengthen her bond with her partner, as outfit coordination was the glue that held Destiny's Child together back in the day.

But the real sign is in the fact that Bey dressed up as Jay in the video for 2006's "Upgrade U," which is proof that the couple's matching-outfits-as-the-low-key-secret-to-relationship-longevity idea took root more than a decade ago.
