VIDEO: Coo Over These Celebrity Babies Born in 2017 The 41-year-old French actress confirmed the news of her second pregnancy last September in an emotional Instagram post after she was swept up into Brangelina split rumors. “Many years ago, I met the man of my life, father of our son, and of the baby we are expecting. He is my love, my best friend, the only one that I need,” she wrote in her 'gram's caption.
