Jay Z serenaded Beyonce from the Made in America Festival stage on Sunday night.

In a video from the event, Beyonce can be seen dancing along to the tune from a special box away from the crowd.
Meanwhile, Beyonce's mother Tina Lawson took to social media to pay tribute to the 'Crazy in Love' hitmaker.
