Camila, 29, is pregnant with the couple's third child. They are parents to son Levi, 3, and daughter Vida, 2, and Matthew, 42, announced the impending arrival of his new little one on Twitter on Independence Day.
Last month the pair wed in a romantic ceremony in Austin, Texas, after six years together.
Meanwhile, being pregnant hasn't stopped Camila from working. She will front a new campaign for the Macy's private clothing label, I.N.C.
