This is the song Ryan Reynolds sang while Blake Lively was in labour

Singing, while your wife is in labour? Well, only Ryan Reynolds could have pulled off such a thing.

In a video posted on designer Michael Kors' YouTube page, the 29-year-old-actress revealed that his superstar husband played Marvin Gaye's song 'Let's get in on' while she was in labour.

While playing a game of Fact or Fiction, the 'Shallows' star asked, "My husband played 'Let's Get It On' when I was in labour. So is it so true or so false?"

To which, the 57-year-old-designer answered, "True."

"My doctor was laughing so hard that I thought she was going to drop our baby," she joked to Michael who guessed correctly.

Blake and Ryan are parents to two daughters: James, two, and Ines, six months.

During the game, she also revealed that she had a childhood crush on David Letterman when she was a little girl, while she had her first kiss at age of 16 on camera.

About the kiss, she said, "My first kiss was in a movie. I was just so terrified."

On the work front, Blake Lively was last seen in thriller 'The Shallows' which went on to be a success at the box office by grossing 119 million USD, against a budget of 17 million USD.
