17 Times Mariah Carey Was An Absolute Diva

Do not speak to Mariah the day before a performance. She cannot under any circumstances speak ahead of performing. If anyone wants to communicate with her they have to do so through writing or sign language so that she can preserve her voice.

In case this isn't enough to preserve her heavenly tone, Mariah takes extra precaution and sleeps with 20 humidifiers in her room to care for her voice. Her bedroom even has a sloped ceiling to allow the water to drip down the sides.

Mariah, vain? Non. Apparently the star went to extreme lengths to ensure her twins were welcomed into the world to the sweet, sweet sound (of her own voice). Mariah admitted she played a live version of her song 'Fantasy' so that they could hear the applause of a standing ovation as they entered the world.

Mariah believes she should be treated like royalty, or even given presidential status, as she stormed out of President Obama's inauguration ceremony because she couldn't understand why she wasn't on the same table as the First Couple...

Never speak over Mariah. During a 2008 Good Morning America performance of Touch My Body one of Mariah's backup vocalists was singing a bit too loud for her liking so Mariah didn't hold back and sang, 'Stop singing my part now, baby.' Awkward.

Always lay out a red carpet for Queen Mariah. Back in 2005, Mariah made reservations to stay at the Baglioni Hotel in London. However, she refused to get out of her limousine until the hotel provided a red carpet lined with white candles. We feel bad even asking for room service...

Her work day is designed to fit around her nap schedule. An idea we'll be pitching to our boss…

Mariah reached next-level diva after appearing on the GMTV sofa back in 2009. After worrying her dress may crease, Mariah refused to sit down without assistance from two producers.

Mariah doesn't celebrate birthdays and manages to dismiss any questions as regards to her age. Mariah told Out magazine, 'I don't count years, but I definitely rebuke them - I have anniversaries, not birthdays, because I celebrate life, darling.'

Mariah is never in flats. She even takes it further than VB as proven when she appeared on MTV's Cribs using gym equipment in heels. She was once even quoted saying, 'I can't wear flat shoes. My feet repel them.' Obv.

In 2009, Mariah Carey was in charge of turning on the Christmas lights at Westfield shopping centre. Mariah reportedly requested 20 white kittens and 100 white doves to be released upon arrival. Just because. Her request wasn't fulfilled.

Don't ever try and put mascara on Mariah. The singer admitted to US Weekly magazine, 'I hate mascara. I never wear it. Whenever a makeup artist tries to put it on me, I throw a fit.' You've been warned.

Don't ever ask her for a selfie with Mariah if you've got a selfie stick. 'That way, I can control it. I don't need to take a selfie with someone from their bleak angle; I don't care for that,' she told Buzzfeed.

Perhaps the most infamous line of all time now. Remember when Mariah claimed she'd never heard of J-Lo? We'll leave it there.

Turns out Mariah feels the same way about lighting as she does her camera angles as the singer explained in her reality show why she wears sunglasses indoors. 'I have a rule which states that I will not be seen in fluorescent lighting without sunglasses,' she said. 'I know it's very Nineties.'

Back in 2008, Mariah was required to fly low-budget for film Tennessee. She surprisingly agreed but of course booked out the entire plane so she could have the cabin all to herself. Goals.

In 2011, Mariah appeared on online shopping channel HSN to sell jewellery and demanded the camera crew only film her from her good angles. She also wasn't best impressed when her earrings fetched for a mere £27...

And the latest Mariah diva story is a rumour that she requests 100 doves in her rider when she's on tour. It's obviously a completely insane request, but diva is as diva does!
