Finally!!! Giuliana Rancic wrote on Twitter early Monday morning, moments after confirming that she is expecting her first child.

The 37-year-old E! News host and her husband Bill, 40, made the baby announcement on The Today Show, a set the two have visited before. Rancic appeared on the show back in October to announce that she had been diagnosed with breast cancer. Earlier this month, she returned to the set, some four months after having a double mastectomy, to discuss fertility options.

Well, we said last time we were on, it's the year of the Rancics. And it really has turned out to be that way, Bill Rancic said on The Today Show on Monday, grinning from ear-to-ear.

Yes, so, we are finally having a baby. Finally! After years of trying, Giuliana added, also with a grin.

The Rancics also added that they are using a gestational carrier, which means that the baby will be their genetic child.

It's our embryo, and we're using a gestational carrier to bring it to term, Bill explained.

The pregnancy news will be featured in an upcoming episode of the couple's reality show, Giuliana & Bill, currently in its fifth season.

It was pretty much one of the best moments of my life, if not the best moment of my life. I mean, it was incredible, we've been trying for so long, we've been through so much. And especially, we just had such a hard year last year with the breast cancer and everything. To finally get that call from the doctor . . . that, you're having a baby, we're pregnant. It was just another world, on another level, Giuliana said on The Today Show.

Last fall, during an attempt to get pregnant through IVF (In Vitro Fertilization), Rancic found out that she had early stages of breast cancer. The petit E! News host later had a double lumpectomy, which was followed by a six-week radiation period. Near the end of radiation, Rancic announced that she was going to have a double mastectomy.

For me, it was important to get the cancer out . . . that's what I wanted to do, just to get it out. At the end, to be honest, all it came down to was just choosing to live, and not looking over my shoulder for the rest of my life, she said at the time.

Following the baby announcement, the couple has been receiving congratulatory messages on Twitter from friends and fans.
