Giuliana Rancic: Motherhood brings tears of joy

NEW YORK - Giuliana Rancic may be known as a trendsetting red carpet regular, but it's the unglamorous side of new motherhood that's got her smiling from ear to ear.

"I never realized how much I would love changing diapers. And how much I would love -- and I'm sorry for being gross -- a poopy diaper. It's like those little things where you go, `Yes! Bill come in here and look how big it is!"' Rancic said in a recent interview.

Giuliana and her husband, Bill Rancic, welcomed their son, Edward Duke, on Aug. 29. The baby was born by a gestational surrogate.

"Being in the delivery room, seeing the baby for the first time, there were just tears of joy, and I just couldn't believe it. You just fall in love like that. And Bill and I, we're literally fighting over who got to hold him first," she said.

The road to motherhood wasn't an easy one for the 38-year-old E! News anchor, whose fertility troubles and miscarriage were documented on her Style Network reality series, "Giuliana & Bill."

Then last October the Rancics announced that she had breast cancer. She later underwent a double mastectomy.

"What's just so incredible is that this year has been truly the hardest year of my life, but it's been the greatest year of my life," she said.

Rancic is now spreading the word about early detection. She's teamed with P&G and the National Breast Cancer Foundation's "Do It for the Girls!" campaign, which urges women to do self breast exams.

She's also launching her new fashion line, G by Giuliana Rancic, on HSN.

A line of baby clothes may be in her future, starting with a few custom garments for baby Edward. She says he'll make a perfect fit model.

"We'll start him working young," she joked.
