With a face like that, who wouldn’t want to share it with the Twitterverse?

Giuliana Rancic and her hubby, Bill, have uploaded some pretty adorable pics of baby Duke in the past, but we think their latest is just about the cutest yet.

“I could stare at this face ALL day :),” the 37-year-old new mom captioned the photo.

And this happy baby certainly has a lot to smile about! Behind-the-scenes footage of his first photo shoot ever — with Life & Style — airs tonight on Giuliana & Bill.

“He’s only two weeks old and he’s already got his own cover — watch out, Brad Pitt!” Giuliana says in the episode.

The proud parents can’t get enough of their little guy, whom they welcomed on Aug. 29 via gestational surrogate.

“I had always heard that when you have a baby it completes your life — and it’s true,” the E! News host told Life & Style during the shoot. “I love my baby, and I love my new role.”
