OMG! How cuteeeee! Here's a video of Beyonce rehearsing for her Grammy performance (with a creepy Jay-Z stand in) and towards the end you can here Blue Ivy say "surfboard." Bey says "Hi Blue Blue" and she starts saying, "Hi Mommy, Hi Mommy." I mean can you even stand it! So presh! And Beyonce's face is just as adorable. Good thing Blue doesn't know what surfboard really means though. HA!
