Video: Awwww, Blue Ivy Sings Along With Mama Bey Drunk In Love During Rehearsals

Beyonce released a video showing her rehearsing her hit song Drunk In Love, the 32-year-old songstress was interrupted by her daughter Blue Ivy, who chimed in with the lyric 'surfboard.'
 'Hi Blue Blue,' Beyonce responded with a big grin on her face, as she stood on stage with choreographer Frank Gatson Jr., who was standing in for her husband Jay Z.

'Hi Mommy,' the two-year-old tot said back, causing Beyonce to close her eyes at the cuteness of the moment, which came as she rehearsed for the Grammys.

 It's unclear as to whether Blue Ivy's voice was pre-recorded or spontaneous, but it still created a priceless moment. Watch video clip below....
