Taking care of a baby isn't easy. Fortunately for Blake Lively, she has husband Ryan Reynolds around when it comes to taking care of 1-year-old James.

But he's not just in her corner. He's there for all the tough stuff!

"He does love the dirty work. He's great and he's so fun about it," she told Hoda Kotb and Kathie Lee Gifford on Friday while visiting TODAY to promote her new shark-attack film, "The Shallows."

As she recalled, "We were changing diapers and he said, 'You've got to get rid of it!'" and she mimicked holding up a dirty diaper. "I said, 'OK!' And he goes, 'No, not the diaper, the child.'"

Aww, we know he's just joking.

But he's more than that to Lively: "He is my best friend, and he's just the best father in the whole world."
