Blake Lively reveals the bizarre song she had playing while giving birth

Blake Lively gave birth to the sound of Marvin Gaye's hit Let's Get It On.

The 29-year-old actress - who has two daughters, James, two, and six-month-old Ines, with her husband Ryan Reynolds - has revealed she gave birth to one of her children while the well-known track from 1973 was played in the background.

During a game of Fact or Fiction with Michael Kors for Glamour magazine, Blake shared: "My husband played Let's Get It On while I was in labour."

Despite the unusual scenario, Blake was happy to hear the familiar tune in the background, admitting it is her favourite song of all time.

She said: "That's like my favourite song, so I'm just gonna go with fact."

And the blonde beauty - who married Ryan in 2012 - revealed the surreal situation even prompted a chuckle from her doctor.

The Café Society star said: "My doctor was laughing so hard I thought she was going to drop my baby."

Meanwhile, Ryan claimed recently that parenting has given him "anxiety".

The 40-year-old actor loves being a father, but he now finds he is constantly in a rush and has to cram things into short bursts of time.

Ryan said: "I think you're just more desperate in everything you do cause you're like, 'I've got 10 minutes to do this, and then I gotta get home for a thing, and a thing, and a thing...'

"There's just no time anymore, so you're hardened by it. Anxiety, I think, that's probably it."

However, Ryan does like to find time to hang out with his friend and Life co-star Jake Gyllenhaal because they have such a great bond.

He recently confessed: "There's a certain harmony that comes when we're both together."
