Cooper, who raises his sons with his former partner Benjamin Maisani, appeared on The Late Show with Stephen Colbert in September, where he talked about the sweet relationship between his two sons.

The journalist noted that he and his older son had an enchanting daily routine that also involved Wyatt's little brother.

“I wake Wyatt up first, and then he wants to come with me to wake Sebastian up, and he likes to get into Sebastian's crib,” Cooper said. “He has this thing now, I don't know where it comes from, where he says, 'I want to smell Sebastian, I want to smell the baby.'”

“And I say, 'Smell the baby.' And he smells the baby's head. And every time he says the same thing: 'He smells like an angel,' and I say, 'Are you from a Christmas special?'” Cooper said, laughing.

“Take the kid to Hallmark!” joked host Stephen Colbert.
