Giuliana and Bill Rancic hosted a baby shower in LA yesterday afternoon, and revealed they are expecting a son via gestational surrogate. The couple's shower invite read "Blue or pink, what do you think?" and guests were kept guessing until the happy couple revealed the gender of their unborn baby.

It's been a long road to starting a family for the E! News host and her hubby, who struggled for years to conceive before turning to surrogacy. They announced the happy news in April, just months after Giuliana underwent a double mastectomy due to a breast cancer diagnosis.

Congrats to the soon-to-be parents!
