Bill and Giuliana Rancic are absolutely in love with their newborn.

The couple welcomed their son Edward Duke Rancic last week in Denver via a surrogate. Edward weighed in at a healthy 7lbs 4oz.

Bill and Giuliana are absolutely ecstatic to be in the company of their new baby boy.

"They are so happy right now. It's beautiful to see," a source told People magazine. "They love that little guy so much. He's so sweet."

After struggles with fertility and a breast cancer battle for Giuliana, the couple decided to enlist a surrogate to help them become parents.

Earlier this year the pair revealed that they were expecting a little boy, and were excited about the prospect of starting a family.

"Our journey has a happy ending," Bill posted on Twitter previously.

"We didn't give up, we didn't quit and we're going to have a good ending to this."
