Kelly Rowland can`t wait to babysit for Beyonce

London: Former Destiny`s Child star Kelly Rowland is looking forward to babysit R&B star Beyonce Knowles` child although she is not ready for kids of her own yet. Although the `When Love Takes Over` hitmaker wants to have kids of her own some day, for now she is excited about being an honorary aunt to her former bandmate`s yet-to-be-born baby, her first child with husband Jay-Z, reported Marie Claire magazine. "I will babysit and change a diaper or two, and then give it back. I do want kids, but every time I think about a little person growing inside of me and getting bigger and bigger and then having to come out... a watermelon coming out of something the size of a lemon is insane to me," she said. Meanwhile, the 30-year-old singer has won praise from fans for her super-slender figure but she says she has to work very hard to maintain her toned physique and never eats after 7pm, much to the annoyance of her friends. "My friends hate that about me. They all want to go out to eat around 9pm and I`m like, `Er, unless I`m going to wait three house for this to digest, I`d rather not`," she added. PTI
