“Lydia’s birthday was in September but we decided to lay low and just have a sweet, intimate celebration with just the two of us,” Hardwick, 49, says. “We were really missing getting together with our friends, though, so we figured we could have an ‘Unbirthday Party’ for her the next month during Spooky Season where we’d set up a screen outside with some cushy seats and watch the newHalloweenfilm (we’re both really big horror fans).”

“All in all, it was an incredible night: catching up with friends we love — some of whom we hadn’t seen in person in two years — sharing the news of our daughter in a way we’ll always cherish, eating cake, and watchingHalloween Killsunder a beautifully crisp, starry-filled October sky.”

“I absolutely love being pregnant,” says Hearst, 37. “I have been extremely fortunate to have an ‘easy’ pregnancy. I have felt really wonderful this whole time and have been lucky enough to be able to continue filming and work on getting the nursery together.”
