(Cover) - EN Showbiz - Kelly Rowland can't wait to be an "auntie" to Beyonc Knowles' baby.

The Destiny's Child bandmates have been close since childhood and treat each other like sisters. Kelly is thrilled Beyonc is expecting her first child with husband Jay-Z and looks forward to welcoming the new arrival.

"I'm so happy for her and her husband [Jay-Z] and just excited to be an auntie - part two. First it was Julez," Kelly told MTV News, referring to Solange Knowles' six-year-old son. "Now it's a new baby on the rise; it's going to be so exciting."

Even though she is pleased that Beyonc is starting a family, Kelly insists she has no plans to follow in her footsteps.

The 30-year-old singer is happy with her life as it is, but has offered her babysitting services.

"Kids!? Unh-unh," she laughed. "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.

"I get to babysit, yes."

Kelly went on to reveal she recently met Beyonc who is due to give birth early next year.

The star was overwhelmed when she saw her friend's growing baby bump.

"It's a wonderful moment," Kelly gushed. "And I got a chance to rub her tummy." (C) Cover Media
