Beyonce and hubby Jay-Z opened up the 56th Grammy Awards with King B's smash, "Drunk In Love." We now have footage of the moments that lead up to the performance, including an impromptu and heartwarming exchange between Beyonce and daughter Blue Ivy.

Beyonce is rehearsing her performance with a Jay-Z stand-in. When it gets to the "surfboard, surfboard" section, the crowd and Mama B can hear Blue Ivy's voice backstage singing along. The rest is some pretty cute stuff between a mother and daughter.

Check out the video above.
