Reynolds’ hilarious prank on Lively during labour

BLAKE Lively and Ryan Reynolds continually prove they're one of the most perfect couples around. And this latest anecdote only adds to that perception.

Mother-of-two Lively has shared just how supportive her husband was while she gave birth - revealing the Deadpool star blasted Marvin Gaye's sexy tune Let's Get It On in the delivery room.

"My doctor was laughing so hard that I thought she was gonna drop our baby," Lively told designer Michael Kors during an interview this week.

It's not the first time Reynolds' delivery room DJ skills have come up. The actor opened up about his choice of soundtrack during an interview on Late Night With Seth Meyers last year. And, basically, his wife didn't appreciate the tune.

"It was like steak knives came out of her eyes. ... Yeah. Real bad," he said.

The couple has two daughters - two-year-old James and six-month-old Ines.

Elsewhere in the chat with Kors, the Gossip Girl star revealed her first kiss was on camera when she was 16 and admitted her teenage crush was a little ... unexpected.

"I had a crush on David Letterman," she said. "He had my dad's sense of humour - that really dry sense of humour and I like that."
