Mary Lynn Rajskub - aka 24's Chloe - on Thursday gave birth to a baby boy, Valentine Anthony. The child is the first for Rajskub, 36, and her boyfriend Matthew Rolph, 28.

Following a delivery that was two weeks after the due date, Rajskub joked, "It was like an episode of 24 with the clock ticking."

Per People, Valentine's gender was a mystery to the couple up until his birth - the pair kept it a surprise, and painted the nursery green. Even with her new arrival, Rajskub will be back for 24's seventh season. While little Valentine may need her, Jack does, too. - Anna Dimond
