New father Ryan Reynolds had some stellar advice for dad-to-be Seth Meyers. The "Deadpool" actor stopped by "Late Night" on Wednesday and broke down fatherhood for the host.

"Just do the dirty work, man," Reynolds said. "You gotta do the diapers, you gotta do the middle of the night thing. A human being will exit your wife. She's done enough."

During his interview with Meyers, Reynolds also revealed to Meyers that he played a prank on his wife Blake Lively in the delivery- something that did not go over well with her.

"I jammed a little Marvin Gaye, 'Let's Get It On,'" Reynolds said. "It was like steak knives came out of her eyes. 'Are you -- right now?'"

"But she was a mercenary. I think I just caught her right in the middle of a contraction," he continued. "She was pretty much making jokes the entire time."

Reynolds and Lively got married in a very secret wedding ceremony in September 2012, according to Page Six. The actress announced her pregnancy in October 2014 and gave birth to a daughter named James two months later.
