Britney SpearsBritney SpearsShe might be a global superstar - but when it comes to impending parenthood, Britney Spears is just like any other mum-to-be.

The singer, who's due to give birth this autumn, has admitted she's nervous about being a mum.

"I've always known that I was going to have a baby one day," she said.

"But there's times when I get a little scared. It's mind-blowing to have a child."

However, she has said she's excited about the new arrival - her first child with hubby Kevin Federline.

"I think it's kind of healing, too, and therapeutic," she admits.

"And all the secrets from your family come out of the closet for some reason. But it's good. They have to come out sometime."

Meanwhile, Brit's been enjoying some last-minute food cravings as her due date draws near.

But instead of the pickles and ice-cream more commonly associated with pregnancy, she's been tucking into fried chicken from Koo Koo Roo, a fast-food outlet in LA.

And she's been washing it all down with plenty of chilled Frappuccinos from Starbucks - staff at her local branch say she's a regular.
