Beyonce surprised us all when she proudly revealed her brand-new baby bump at Sunday night's (Aug. 28) 2011 MTV VMAs -- hugging her belly on the red carpet and at the end of her live performance at the main event.

Now, longtime friend and former Destiny's Child bandmate Kelly Rowland is speaking out about Beyonce and hip-hop husband Jay-Z's baby-to-be, and her take on what Queen B might be like as a mother.

"I think she'll be an incredible mother," Rowland told E! News at a post-VMAs party. "She's always been motherly. I think that takes after so many traits from her mother [Tina Knowles].

"I just think it's going to be so natural for her. It's natural for her now. I can't believe this to this day," Kelly admitted.

Rowland told People that she knew of her pal's big news before last night's announcement. "I have known for quite a while, and she's happy, and Jay is happy, and that's all that counts," she revealed.

Rowland added that the parents-to-be have already started talking about baby names!
