Beyonce's Mom Tina Describes Twins Rumi & Sir's Personalities!

Beyonce and Jay-Z welcomed their twins, Rumi and Sir, seven months ago and now, their grandma Tina Knowles-Lawson is describing their individual personalities!

“This is my first experience around twins, and they’re so different, and their personalities, and they are wonderful,” she told Us Weekly over the weekend. “Other than the boy has a stare, like a mean mug, like Jay sometimes, which is so cute, and the girl, she’s just so happy all the time and so sweet. They are just adorable!”

Since their birth, we’ve seen only one official photo of the twins. Their birthday is June 13.
