Giuliana Rancic Dances in a Onesie Outfit to Make Baby Duke Laugh

Giuliana Rancic will do anything to make her little boy Edward Duke Rancic smile — even if it leads husband Bill Rancic to declare her crazy! Donning a hilarious gray adult-sized onsie outfit on the Tuesday, July 23 episode of the couple's Style reality series Giuliana & Bill, the first-time mom, 38, attempts to show off her dance moves in order to impress Duke, 11 months.

"I'm onesie dancing! That's sexy," Giuliana, 38, says in a clip from Tuesday's show, as she bops around the couple's kitchen eating whipped cream straight from the can.

Giuliana Rancic makes her baby Duke laugh by wearing a onesie outfit and dancing around on the July 23 episode of Style's Giuliana & Bill.

While the E! News anchor's antics get a smile out of her son, Bill isn't as easily impressed. "This is what drugs do," he jokingly tells their baby. "Never do drugs! Yeah, she's crazy — I know."

Muses Bill, 41: "I've got two children!"

Joking aside, the couple will celebrate a well-deserved milestone when Edward Duke turns 1 on August 29, and Giuliana — who battled breast cancer and numerous failed IVF attempts before welcoming her boy via surrogate — has grand plans.

In a joint Us Weekly interview with her husband July 16, Giuliana hinted she was considering an Italian-themed fete. "He's half Italian, so maybe we'll do an Italian theme. That'd be cute. It'll be like The Godfather," she told Us, referring to the 1972 film that follows a New York City-based Italian family with Mafia ties. Bill, however, wasn't into it. "That's good role model, someone to look up to: [crime boss] Michael Corleone!" he joked of the character portrayed by Al Pacino. "It is not a good idea!"

Giuliana & Bill airs Tuesdays at 8 p.m. (EST) on Style.
