No One Was More Proud of Beyoncé at the Grammys Than Jay Z and Blue Ivy

Beyoncé completely slayed at the Grammy Awards on Sunday night, but one of the cutest moments had to be her family's reaction after her performance. After giving a moving medley of "Love Drought" and "Sandcastles" from her Grammy-nominated album Lemonade, her husband, Jay Z, and their daughter, Blue Ivy, just couldn't contain their joy as they gave her a standing ovation. Not only did Blue — who was perfectly dressed as the late Prince — look so proud of her mom, but Jay Z even looked like he had a tear in his eye. Aww!
