Today anchor Jenna Wolfe and her girlfriend Stephanie Gosk have welcomed their second child together -- get the details

Another addition! Today show weekend anchor Jenna Wolfe and her girlfriend Stephanie Gosk have welcomed their second child together.

"Quinn Lily Wolfeld-Gosk born at 4:06 6lbs 12ozs Everyone is great," Gosk captioned a pic of their little one on Wednesday, Feb. 4. "Woohoo!!"

Wolfe, 40, and NBC News foreign correspondent Gosk are already parents to daughter Harper, 17 months. Back in August, Wolfe announced that she was pregnant with baby No. 2.

"Harper is going to be a big sister!" she revealed on-air at the time. "I figured I got pregnant, I did it right the first time. I'm just going to do the exact same thing again and we're going to hope for the best."

Hours before her tot's arrival, Wolfe tweeted that she was in labor. "It's time!!!" she wrote. "This little one's as stubborn as her mama (me)," she added later in the day. "Apparently she's going to come out when she's good and ready."

Last month, Wolfe also shared her joys about motherhood in a Today show blog post. "One of the best things about parenting is collecting all the firsts: the first smile, the first sneeze, the first haircut, the first holiday," she wrote. "Enjoy collecting the firsts, big or small, while you can. Photograph them, talk about them, lock them away in your memory because there will undoubtedly be a time when you'll need just a little nostalgia to hold your hand and get you through your day."
