24 star and comedianMary Lynn Rajskub and her boyfriend Matthew Rolph, 28, have welcomed their first child. Son Valentine Anthony Rolph arrived on Thursday, July 24th, weighing in at 9 lbs, 5 oz. Born almost two full weeks after the due date, Mary Lynn says waiting for her baby boy "was like an episode of 24 with the clock ticking."

Mary Lynn, 37, announced the pregnancy in January, saying that the first trimester "felt like a really bad hangover." In April, she said she and Matthew felt the baby’s sex was one of the "great mysteries of life," so they were keeping it a delivery surprise. Last month, she celebrated her baby shower.
