It turns out blue is the new black for Jason Biggs!

The Orange Is the New Black star and his wife, Jenny Mollen, welcomed their first child, son Sid, on Saturday, Feb. 15, they announced via Instagram.

Born at 5:33 p.m. in Los Angeles, Sid weighed in at 8 lbs., 8 oz. and is 21¼ inches long.

“Full head of hair, huge penis,” Mollen, 34, jokingly captioned the first photo of their son. “Mom is doing great and a fan of dilaudid (pain reliever).”

On a more serious note, “We are incredibly grateful to all the nurses and staff at Cedars-Sinai,” she adds. “Everybody was top-notch.”

Mollen shared the happy news in a series of videos that show the trip to the hospital, the labor, the epidural and the eventual unexpected c-section.

“You did amazing, sweetie. I’m so proud of you,” Biggs, 35, says in a clip following the delivery. “He’s beautiful — pretty damn cute.”

Originally due Feb. 4, Mollen had humorously been sharing her frustration with being 41 weeks along.

“I feel like I’ve been pregnant since the mid 90s,” she Tweeted recently, followed by, “I think I might have my second baby before I have my first.”

During a visit to Chelsea Lately in July, Biggs confirmed the couple were expecting by showing a photo of his wife’s blossoming bosom. “Her breasts are very big these days. Would you like to know why? ‘Cause I put a baby in her belly!” he joked.

The pair have a few low-key months before June, when both have projects hitting — the second season of Orange Is the New Black is set to premiere, while Mollen’s book, I Like You Just the Way I Am: Stories About Me and Some Other People, will be released.

Biggs and Mollen were married in April 2008.
