NBC anchor Jenna Wolfe announced Wednesday that she and her girlfriend Stephanie Wosk are having a baby girl, and new details have emerged that the couple is engaged.

A Los Angeles Times report indicated that the couple have been together for three years, yet they never publicly announced their same-sex relationship.

"My girlfriend, Stephanie Gosk, and I are expecting a baby girl the end of August," Wolfe wrote in a blog post. "As of this week, I am about five months pregnant."

Gosk, who's a foreign correspondent for the network, sat with Wolfe for an article in People which will announce the news this week in the magazine.

"I don't want to bring my daughter into a world where I'm not comfortable telling everyone who I am and who her mother is," Wolfe, 39, told the magazine.

The couple decided Wolfe would carry the child and used artificial insemination with an anonymous donor.

"She made the first four months brutal for me ... B-R-U-T-A-L," Wolfe wrote in what is her first blog post about her pregnancy. "There were days when all I could eat were Saltine crackers, Apple Jacks dry cereal and plain pasta. Let's just say I have a newfound respect for any woman anywhere who tells me they've experienced morning sickness."

Wolfe hinted on Wednesday via her Twitter account that she was about to reveal some news.

"Well... Here we go!! @todayshow," she tweeted.

Gosk a journalist, graduated from Georgetown University with an economics degree and served time in the Peace Corps. She started her journalism career as an off-air producer for ABC, covering the 2000 presidential election.

She later served as a producer at ABC, producing and reporting stories on the Iraq War and traveled overseas with the U.S. military.

"Stephanie, a foreign correspondent here at NBC, spent years in war-torn countries, risking life and limb in the most dangerous places on earth to tell amazing stories. ... Between the two of us, we've seen and we've done more than most will in a lifetime," Wolfe wrote in her blog.

In an interview with People, Wolfe called her relationship a "miracle" because of the couple's busy schedules.

"We were constantly on the road, juggling a thousand balls at once," Wolfe told People
