"My little darling, know that you are cherished beyond measure and surrounded by love from the moment you graced us with your presence. A True Gift from God 🙏🏾, blessed ! Welcome Babyboy. 💙🍼✨ #mumoftwo ❤️💙," she wrote, adding, "It’s never too late to become a mother 🙏🏾." The star has previously shared just a handful of glimpses of her daughter, whom she welcomed with an announcement on Instagram in May 2021. Naomi Campbell/Instagram; Randy Brooke/Getty Campbell, who was 50 when she welcomed her daughter, shared last year that she encourages her older friends not to "hesitate" to have children. "I always knew that one day I would be a mother, but it's the biggest joy I could ever imagine. I'm lucky to have her and I know that," she told British Vogue as she appeared on March 2022 cover alongside her then 9-month-old daughter. Campbell explained that she has a new "completely selfless" attitude with motherhood and she has no issue with the 50-year age gap between her and her daughter, even admitting that she's encouraging her older friends to have babies as well. "I'm telling them all, do it! Don't hesitate!" she added.
