Since Beyonce revealed her twins, Sir and Rumi, last week, the world is wondering how her other daughter Blue Ivy is handling the latest additions.

Well according to grandma Tina Knowles, she is taking on the role of “big sister” very easily.

“She’s very proud and excited. She’s a good big sister, she really is. She cares for them a lot,” Tina said to Entertainment Tonight. (video above)

She also spoke about the Hollyrod Foundation: “It’s very important because this is such a great cause and it assists families in need, people that are affected by Parkinson’s disease and autism, and Holly [Robinson Peete] is just such an amazing woman,” she said. “I’m just thrilled that they do this, and I’m excited about it, because it’s my first [event for the organization].”
