Rowland was chatting with BANG Showbiz about Beyoncé’s baby shower at the Cosmopolitan Ultimate Women of the Year Awards 2011 in London.
“I’m so happy for my sister and her husband. They’re so happy in this moment right now, as they should be. They’ve made a little bundle of love, I’m so excited for them,” she said.
“I have no idea what I’m going to buy Beyonce at the baby shower because Jay is going to buy that little girl every single thing possible. She won’t be spoiled but she will be very well looked-after.”
“I think she’ll be very well behaved,” Rowland added. “Her parents will make sure of that.”
Beyonce and Jay-Z are reportedly building a 2,200 square-foot nursery at their NYC pad.
The singer is due to give birth in February.
