Mariah Carey – To applause

The pop diva decided to bring some of the magic from her live performances into the labor ward when she welcomed her twins Moroccan and Monroe in 2011.

She played the recording of her 1995 live concert as she wanted her babies to come into the world at the moment of applause.

Her then-husband Nick Cannon recalled: "It was definitely over the top. I was the manager of the whole production."
