They demanded meetings with Vladimir Putin and requested mannequins with PINK HAIR?! You'll never believe these outrageous diva demands!

Talk about high maintenance. Whilst some celebrities remain humble, others just can't help but let fame and fortune go to their heads. From Pri-Madonna behaviour and supermodel tantrums to Lady Gaga’s completely gaga requests, you won’t believe these outrageous diva demands…

Back in 2005 Mariah Carey refused to get out of her limousine until London’s Baglioni Hotel provided a red carpet that had to be lined with white candles. Speaking about being a high maintenance star, Mariah said: "I have had diva moments and then people can’t handle it.”

The 90s supermodel hasn’t always show model behavior. In 2007, Naomi pled guilty to assaulting her maid by hitting her on the head with a cell phone. Then, in 2008, she requested to delay a flight from London to Los Angeles because one of her bags went missing, and in 2014 during filming of ‘The Face’ she demanded no staff were allowed to talk to her unless she said hello to them first.

Lady Gaga must have been completely gaga when she once requested a mannequin with puffy pink hair down below. Her other not so strange request concerns bottles of water and making sure each room she stays in provides 28 refrigerated bottles of water and 28 at room temperature. Documents which were obtained in court by her former assistant who was suing Gaga for unpaid wages of $300,000 revealed her diva demands.

The ‘Roar’ singer has a thing for egg shaped chairs as each dressing room must contain “two cream-colored egg chairs, one of which should have a footstool". Katy also expects a bowl of tortilla chips and a bottle of Pinot Grigio to be waiting for her in her dressing room after she’s done with her performance. She also requests to have a private dressing room all to herself that must be filled with pink and white flowers but under no circumstances carnations as she absolutely hates them. Revealing why she has such specific requests, Katy said: "If you lived on the road every single day and you were in and out of hotels, don’t you want comfort? Don’t you want some sliced turkey?”

The ‘Easy On Me’ singer, wasn’t exactly the easiest of guests during her stay at the UK's Soho Farmhouse hotel back in 2016. Adele - who was staying with her now ex-husband Simon Konecki and son Angelo - sent staff practically on a wild goose chase to a pizzeria in Kensington which was 140 miles away. When they brought back the pizza four hours later, Adele was fast asleep and never even took a bite.

The pop princess had her ultimate diva moment when photos of Ariana surfaced online that showed her being carried by her tour manager. However, Ariana takes pride in her diva reputation. She said: "If you want to call me a diva, I’ll say, 'Um, well, cool.’ Barbra Streisand is a diva, that’s amazing. Celine Dion is a diva, thank you.”

The Queen of Pop took a 200 person entourage with her around the world whilst on her 2012 'MDNA Tour'. This included 30 body guards, a yoga instructor, an acupuncturist and vegan chefs. After a show in Portugal she insisted on ridding her dressing room of DNA by a sterilisation team.
