Kelly Rowland 'Excited' To Be Beyonce Baby's 'Auntie'

Kelly Rowland is thrilled that her sister in life and music, Beyoncé Knowles, is pregnant with her first child — but that doesn't mean K.Ro's ready to take on 40 weeks of morning sickness, strange cravings and swollen feet.

"I'm so happy for her and her husband [Jay-Z] and just excited to be an auntie — part two. First it was Julez," Rowland told MTV News, referring to Solange Knowles' 6-year-old, when we caught up with her on her tour bus during the New York leg of Chris Brown's F.A.M.E. Tour. "Now it's a new baby on the rise; it's gonna to be so exciting."

But when we suggested Kelly might be the next to bare a bump on MTV's VMA stage, the onetime "Destiny's Child" diva nearly spilled the blue plastic cup of post-concert something-something she had been sipping.

"Kids!? Unh-unh," she laughed, tucking a jumpsuit-clad leg firmly underneath her as a towering pair of heels lay on the floor of the warmly lit bus. "I'll help take care of my 'sister' and her husband's baby first. I'm not ready for babies yet. I can watch them take care of this little baby."

Still, Rowland said she'd have no problem pitching in on diaper duty when the superstar couple needed to get away for one of their well-documented date nights. Whether they're sharing a plate at Nello's in NYC or heading to Brooklyn to cheer on the Nets, B and Hov can count on Kelly. "I get to babysit, yes," she smiled.

"It's a wonderful moment," the "Motivation" singer added. "I just saw my sister today, and I got a chance to rub her tummy."
