"She's beautiful," the proud nana told PEOPLE Magazine at the Runway to Win fundraising reception for Barack Obama in New York. "She's doing great!"
Knowles went on to gush about the "amazing" experience of welcoming her very first granddaughter into the family. "It's the second best job I've ever had," said Tina (we're guessing behind being a mother to Bey and her sis Solange).

Guess we'll all have to wait until Jay and Bey release official photos of Baby Blue to see if she got her mom's welcoming smile or her dad's piercing eyes!
