Jenna Wolfe, the weekend anchor on the “Today” show, makes a living by reporting news stories from around the world, but on Wednesday morning, she broke some news of her own. During a special appearance on “Today,” and in a blog post on NBC’s website, Wolfe revealed that she is gay, pregnant and expecting a daughter at the end of August with her girlfriend and fellow NBC journalist Stephanie Gosk.

"Of all the jaw-dropping, head-turning and eye-popping things I've ever told my friends and family ('I swam with killer sharks,' 'I jet-packed 30 feet out of the water,' 'I scaled the tallest building in Canada'), nothing garnered more shock and awe (and, yes, some tears) than when I told people I was pregnant," she wrote in her blog post, the first of many installments. Details surrounding the child’s paternity remain unclear.

"Just writing those words -- 'I'm pregnant' -- is surreal to me," she continued. "After all, I was never the kid that ran around playing house. I never had daydreams about being a mom and raising a family. ... As a kid, I would have chosen raising my adrenaline over raising children any day of the week. But then a funny thing happened on my way to adulthood. ... I grew up."

Both Wolfe and Gosk -- who have reported on "the most dangerous places on earth" -- are known thrill-seekers. "And yet both of us agree that THIS little girl will be the biggest and best adventure of our lives," the mom-to-be wrote.

Wolfe claims to be amateur when it comes to babies and it could be part of the reason she’s so shocked. "I've never changed a diaper. I don't know how to decorate a nursery. I don't really understand what a breast pump is. And don't get me started on the feeding schedule," she said.

But she’s ready for the experience. "Something just sort of told me it was time. Two years into a great relationship we felt like we wanted to share our adventures with a wide-eyed, little person," she wrote in her blog. "The more we talked about it, the better the idea seemed. And so in December, we embarked on Operation Baby. And might I just add that despite the morning sickness, it's been the best decision we've ever made."
