How Adorable: Blue Ivy Busts In On Beyonce’s Grammy Rehearsal!

Her live rendition of “Drunk in Love” was a steamy start to the 2014 Grammy Awards, but Beyoncé Knowles' rehearsal was a whole different ball game.

While running the routine, Knowles got sidetracked when her daughter Blue Ivy Carter managed to grab a microphone and started singing along.

Blue chimed in during the “surfboard” part of the track and at first Bey was able to stay in character.

But when the little darling began saying, “Hi mommy!” over and over, the “Bootylicious” mama couldn’t help but crack a smile.
