Bill and Giuliana Rancic.

Thrilled ... Bill and Giuliana Rancic.

Giuliana and Bill Rancic are having a baby.

The child will be born later this year via a gestational surrogate, meaning the baby will be genetically theirs but carried by another woman.

Last year, 37-year-old Giuliana announced she had breast cancer and later underwent a double mastectomy. She did not need chemotherapy.

Giuliana and Bill's struggles to conceive a baby have been well-documented with failed IVF treatments and a miscarriage.

Giuliana is the host of E! News and co-host of Fashion Police. Bill is a 40-year-old entrepreneur and motivational speaker who won the first season of Donald Trump's The Apprentice.

Together, they co-star in a reality show on the Style Network called Giuliana & Bill. Much of the show has been devoted to their fertility issues.

We are so thrilled that our prayers have been answered," she told E!. Adds Bill, "We are absolutely ecstatic to be sharing this with everyone who has been following our journey."
