It's a Boy for Mary Lynn Rajskub!

"It was like an episode of 24 with the clock ticking," jokes Rajskub.
Valentine, who weighed in at 9lbs., 5oz., is the first child for Rajskub, 37, and her boyfriend Matthew Rolph, 28, a physical trainer.
The couple, who met while Rajskub was performing a stand-up comedy gig, disagreed over whether or not to find out the baby's gender. Rajskub won. "I wanted it to be a surprise," she says, "and Matthew wanted to find out."
To make a gender-neutral nursery, the couple designed the baby's bedroom in their San Fernando Valley home with the color green. "Matthew and I did a painting together, and [the nursery] is based on the painting we did, using those colors. It's vintage, and eclectic."
Rajskub, who will return to TV in January for 24's eighth season, says pregnancy has been, "scary and exciting," especially given all the advice pals volunteer. "The closer I get to having this child," she told PEOPLE at her baby shower in June, "the more I'm letting advice go in one ear and out the other. Everyone has their own thing."
