The couple, who recently tied the knot on June 2 at Barrymore's Montecito, California estate, spoke about their yet-to-be-born first child during a speech at the ceremony, reported Contactmusic.
"Everyone knows the baby's coming, so there wasn't much talk about it. Will said something like, 'I'm excited to marry you. I'm excited to meet the newest member of our family'. Both Will and Drew were involved with the whole wedding process, equally. It was insanely gorgeous," a source said.
Barrymore and Kopelman are yet to announce the child's news in public.
