Mariah Carey demanded an Ali G DVD be played during a recent massage.

A source close to the singer told the Daily Mirror newspaper: "As Mariah had her aches and pains kneaded, she watched the same flicks on repeat. Mariah' a huge Ali G fan and finds his humour helps her to relax."

The 'American Idol' judge paid $1,500 for the treatment in the comfort of her own home.

Mariah, 42 - who has two children, 21-month-old twins Monroe and Moroccan, with husband Nick Cannon - is renowned for her demanding antics and an entourage including bodyguards, an assistant, hairstylists and a rumoured water bottle carrier.

In 2005, she requested London's Baglioni Hotel roll out a red carpet lined with white candles as she arrived for a 20,000-a-night stay at 2am in the morning.

The 'We Belong Together' hitmaker also once famously revealed she slept with 20 humidifiers around her bed.

She explained: "Basically, it's like sleeping in a steam room. The bed is all towelling cloth, the ceiling is sloped so the water can't fall on my head, and it drips down to my side. My TV is behind glass."
