Grammy Awards: Blue Ivy Tells mom Beyonce and dad Jay Z to stop clapping 

Jay Z and Beyonce might seem like the coolest parents around, but they still manage to embarrass Blue Ivy.

The precocious six-year-old took charge at the Grammys on Sunday night and ordered her famous mom and dad to chill out.

With a steely gaze, and a nonchalant 'calm down' hand gesture, she immediately brought them to heel as they clapped enthusiastically at her side.
