Kelly Rowland attends the House of Hype's 2011 MTV Video Music Awards After Party at the SLS Hotel on August 28, 2011 in Los Angeles

*Beyonce’s former Destiny’s Child band mate Kelly Rowland says she had a head start on the singer’s pregnancy announcement at Sunday’s MTV Video Music Awards.

“I have known for quite a while, and she’s happy, and Jay is happy, and that’s all that counts,” Rowland, 30, told People Sunday at the House of Hype VMAs afterparty. [See pics.]

Asked how Beyoncé, 29, will be as a mom, Rowland replies: “I think she’ll be an incredible mother, because she’s always been motherly. I think that she takes after so many traits from her mother. And I just think it’s going to be so natural for her. It’s natural for her now!”

Rowland added that the happy couple has already started talking about baby names, but of course kept mum on that front.
