Jessica Simpson loves to "show off" her baby bump.

The 31-year-old singer-and-actress is expecting her first child with fiance Eric Johnson, and though she didn't announce her pregnancy until late last month, she is now happy to flaunt her changing shape.

She said: "I like wearing things more fitted. You want to show off your bump! It's just so fun. You don't want to wear muumuus so you can moo around town."

"I'm definitely bigger than I've ever been [but I've] never felt so connected with my body in my life."

The 'Fashion Star' mentor also claimed she plans to give birth while wearing her high heels because she isn't ready to give up her beloved footwear.

She told the new issue of Us Weekly magazine: "I'm probably going to deliver my baby in these [four-inch heels]. I went to the doctor yesterday and he said, 'You're gonna need to get out of those heels!'

"I was like, 'Excuse me! I'll be delivering in these heels!"

Jessica announced her pregnancy on Halloween (31.10.11) by tweeting a picture of herself dressed as a mummy to confirm she was "going to be a mummy" and she thinks it is something that will make her child think she is a "cool" parent.

She said: "My kid's going to think I'm pretty cool. This is a cool thing to welcome him to the world with."
