The couple already have a 2-year-old daughter Maggie, who has been preparing to become a big sister. "She's obsessed with dolls," Hayes told PEOPLE in January. "She wants to wrap them up and put them to bed. They're all called Barbara. She even calls the baby 'Baby Barbara.' "
While there's still no word from CBS as to whether or not Worst Week will be picked up for another season, Lilah came at a perfect time for her mom's work schedule. "If we get picked up, we won't start filming until August, so I can have a few months with the baby," says Hayes.
Meanwhile, she patiently awaits the news. "I already have good news coming in May," she said in January, referring to her baby's birth. "If we do get to do the show, it'll be an added bonus."
