Ryan Reynolds had to play a song while Blake Lively was in labour

Well, now we know why Ryan Reynolds and Blake Lively have such a happy marriage. It doesn't look like Lively could get sick of her husband's sense of humour and comic timing any time soon. Which is why it turned out to be extra funny when she revealed that her husband played Marvin Gaye's 1973 jam Let's Get It On while she was in labour with their first daughter, James.

During a round of Glamour Games with designer and good friend Michael Kors, Lively and Kors let loose on quite a few facts about their lives. Lively revealed that when the baby was being delivered, her husband decided to play the Marvin Gaye song to 'set the mood'.

The Deadpool actor has spoken about this in the past, saying that his wife's reaction to the song was 'not pleasant' and said that 'she was probably having a contraction at the time'. Lively herself said "My doctor was laughing so hard that I thought she was going to drop our baby".

The Glamour Games segment with Kors also led to a lot more facts spilling out about the two, including the fact that Lively's first kiss was on-screen when she was 16, Kors did jello shots with Jennifer Lopez, Lively's first dog was named 405 after the highway, and that her childhood crush was David Letterman.

Lively and Reynolds have two daughters - James (2 years) and Ines, (7 months).
