One person who’s no doubt over the moon to welcome another baby into the family? Flynn, who adorably didn’t even let the ink dry on his mom’s marriage certificate before asking for a sibling.
“He’s so excited that Evan and I had been together for a while and he was like, ‘When are we going to have another baby brother or sister?’ And we were like, ‘Look, we’ve got to get married first,’ ” Kerr told Jimmy Kimmel in February 2018, while pregnant with Hart.
She continued, “So the day after the wedding, he comes running in and he’s like, ‘Mommy, is it in there?’ I was like, ‘Honey, give it a minute,’ ” adding that Flynn “has a mischievous personality like me. He also has my little chin.”
