Supermodel Naomi Campbell announced she has a newborn son on Instagram on Thursday. “My little darling, know that you are cherished beyond measure and surrounded by love from the moment you graced us with your presence,” she wrote alongside a photo of the infant. The 53-year-old catwalker already has a 2-year-old daughter. She has not talked about how the children were conceived or delivered but noted in her Instagram post that “it’s never too late to become a mother.”
