The parents-to-be were both wearing PRVCY jeans and were seen embracing and kissing each other before getting into their black convertible Porsche.

The super-slim Fashion Police host revealed just a hint of her teal bra underneath her loose black tank, and she finished off her red-hot look with a sexy pair of black lace-up, peep-toe booties.

The 37-year-old anchor wore her caramel hair out in a smooth blow-dry and kept her make-up fresh and neutral.

Bill, 41, showed his Chicago roots with his Cubs hat and wore a light blue button-up tucked into shiny blue jeans and laceless Converse sneakers.

Her husband of four years will actually be co-hosting E! News with her tonight, and the constant togetherness seems to only heighten their love for one another.

The beaming lovebirds, who've also co-authored a book called I Do, Now What?, are not only celebrating their new addition, they are thrilled that Giuliana's contract with E! was just extended through 2015.

Things were not always so rosy for the pair -- Giuliana underwent a double mastectomy after being diagnosed with breast cancer last year.

The Apprentice star will serve as disciplinarian in the house if the couple's baby, now six months along, ends up being a boy.

'The reason being that when you have a mother-[son] bond, he’s like your prince — you don’t want to discipline him,' she told People Magazine.

'And then there’s daddy’s little girl, he’ll never want to discipline her. But to be honest, chances are I will discipline, because I’m a crazy Italian chick.'

E! News recently published one of the couples' adorable baby shower invitations featuring a guessing theme by headlining the invitation with a question: 'Blue or Pink: What Do You Think?'

Underneath the playful question was a pink 'g' for Guiliana in pink script and a 'b' in blue for Bill. The front cover of the invitation gave the date of the party as June 17th, but the location wasn't divulged.

The baby is due at the end of the summer and the Rancic's already know the gender, but they're not saying. At least not until the shower.

'Here's the thing,' Rancic told E! News earlier this month.

'I don't know how long we're going to be able to keep it a secret, but it's like the only thing in our lives right now that's a secret...  It's fun having something between the two of us.'

Giuliana and Bill plan on trying for a second child once she's clear of the cancer treatments in five years.

'Five years puts me at 42, and a lot of people have kids at 42. So I'm definitely going to try again,' she said.
