Betty Gilpin is opening up about her birthing scene in the new Jennifer Lopez and Brett Goldstein romantic comedy “Office Romance.” “Honestly, I was pretty freaked out when I first saw the prosthetic vagina,” Gilpin told me at the film’s Los Angeles premiere. “I had a nervous breakdown and then I was like, ‘Oh, but I’ll be holding the ultimate working mom’s hand, Jennifer Lopez, so what could go wrong?’” Gilpin explained how it all went down.
