Madonna has made a big threat against people smoking around her, stating that she would pull out of a performance if concert-goers did not put out their cigarettes.
The singer is well known for her range of diets and healthy living but seems to have taken it one step further by taking a diva-like stance about people who smoke in her presence.
Before a gig in Chile last week, the Material Girl smelled someone smoking a cigarette and refused to continue with her sound check until it had been put out. And the Mirror report that a fan in the crowd managed to record the whole thing on video.
"There are people smoking right now. No smoking! If you're going to smoke cigarettes, I'm not doing the show," Madonna told the crowd.
When the people watching her perform refused to stop smoking, possibly because she was talking to them in English and they were in a Spanish-speaking country, she continued to rant.
"You don't care about me? I don't care about you. All right?
"Are we going to play that game? I'm not kidding. I can't sing if you smoke. If you love me then don't smoke. No smoking!"
Madonna then stormed off the stage to boos from the crowd.
But the pesky smokers must have cleared up their act in time for the show itself, as the concert still went ahead.
Mischievous (and, let us not forget, rather odd) pop star Robbie Williams' list of requirements reads like the world's most devilish treasure hunt. Kumquats (tiny oranges), a bonsai tree, four ashtrays, clean underwear... and a framed photo of Bob Holness (former host of cult quiz show Blockbusters). Seriously Robbie - couldn't you just bring your own? (Pic: Getty)
Plenty of people have a problem with 50 Cent, but the rapper insists on there literally being no beef whenever he plays a gig. "There is to be no beef (except where noted) or pork in the food or vicinity of 50 Cent's dressing or catering rooms", bellows his rider request list. He also asks for eggs "made to order", proving that he has high connections in the glamorous world of battery farming. (Pic: jpistudios.com)
Forget Van Halen's legendary M&M-related request - Billy Corgan of Smashing Pumpkins fame has submitted the world's weirdest rock rider. At a show in Australia, he demanded a defibrillator and an ambulance, of all things, before warning lackeys not to enter his field of vision while he's performing. (Pic: Getty)
Given Britney's past misdemeanors, i.e. waving umbrellas around like a bald-headed nutter, you might expect the pop star's list of backstage demands to be fairly crazy. And guess what - you'd be right. It's not the two boxes of Pop Tarts, Froot Loops cereal, cable television, two 6-foot sofas and odor-free carpet we find unusual, it's the demand to have a private phone line installed in every room and her decision to fine her promoter $5,000 for any unauthorized calls she receives that strikes us as a little diva-ish.

Clearly there is an ideal temperature to keep your vocal chords and enormous mandible in full working order - as according to Celine Dion's rider her dressing room must be a precise 23°C. She also requests parking for 20 trailers, 10 buses and three stretch limousines. One assumes that she must carry all her fans on tour with her too. Getty
Still, all of these celebs are mere pretenders to Grace Jones's throne when it comes to spectacularly diva-ish behaviour. For example, she insisted on having a caviar facial on every night of her January tour. And at the MOBO awards she demanded to be driven right up to the stage instead of walking. Now that's how to do it. Gaga has a lot to learn. (Pic: WireImage)
"I'm still Jenny from the block", Jennifer Lopez once declared to a world of raised eyebrows. After all, people who are down-to-earth wouldn't insist on massive trailers, more white flowers than an Elton John party and having their coffee stirred counter-clockwise when at a charity single recording session. And she expects us to believe that her love don't cost a thing! AP
Devon-born drawler Joss Stone issued an 11-page list of must-haves prior to a performance at a festival near Liverpool in 2007. Not only did she request a dozen roses with their thorns removed and plenty of Miracle Whip, but it was pointed out that the starlet would only eat from china plates placed on a tablecloth. Meanwhile, the punters formed queues at Botulism Burger. (Pic: Getty)
What does the Donatella Versace of Pop have on her rider? Well, Lady Gaga requests plenty of cheese - but only if it's entirely odourless. This would indicate that she likes her dairy products to be entirely flavourless as well, but we guess that she's rarely been troubled by good taste. Besides, her cheesy music stinks quite enough.

She may be Simon Cowell's most successful X Factor act ever, but does that really entitle Leona Lewis to dictate what everyone else should eat? According to reports from 2010, the Bleeding Love beauty is such a strict vegetarian that she forbid all her staff from eating meat when she was on tour - even if they brought their own food from 'outside'. We can image there were more than a few disgruntled roadies on that trip... (pic: bauergriffinonline.com)
In a bid to prevent her bony bum-prints turning up on eBay, Madonna is said to demand a brand new toilet seat at every concert she plays before having it smashed to bits after use. She also requires three candles to protect her from bad vibes, possibly from those who've forked out £120 to hear her eschewing classics like Holiday for her cover of American Pie. Bauer Griffin
Where to start when it comes to diva tales about our Mariah? The most memorable recent one was that she requested 20 white kittens and 100 white doves when she turned the Christmas lights on at Westfield - but was refused on health and safety grounds. (Pic: AP)
At first glance, rock star Marilyn Manson's list of back stage requirements could belong to any fairly fussy celeb. Air-conditioning? Of course. Haribo Gummi Bears? Why not. Absinthe, popcorn and Doritos? I'll pop to Sainsburys. But a bald prostitute with no teeth? We really feel sorry for the runner handed that one... (Pic: FilmMagic.com)
This may come as a shock, but apparently Michael Buble is a little precious about his personal grooming. Although for precious, you could just as easily read 'demented'. The crooner once asked for a ludicrous 84 dressing-room towels to be delivered. He also wanted his roast beef to come in a 'shrink-wrapped resealable pouch', presumably to nibble on later. Getty
Streets front man Mike Skinner has long been hailed as a man-of-the-people. But we're not sure how this tallies with his apparent demands for a vintage merry-go-round horse, a choice of pillows and music being played on his arrival at the Myhotel in Brighton. Sounds like a grand's worth of stuff does come for free... (Pic: WireImage)
The Beatles is definitely one of the more exact divas on our list. He demands 19 leafy six-foot plants, four leafy four-foot plants, vegetarian catering only and absolutely no animal by-products anywhere - including the furniture and carpets. Meanwhile, we wonder how much carbon monoxide is pumped into the atmosphere getting all this stuff delivered. Just sayin'... (Pic: Getty)
The secret to Prince's enduring youthful looks and songwriting prowess may well be contained on his request list. The legendary songwriter demands a physician be on hand at all times, particularly so he can be injected with vitamin B12 whenever he wants. Reportedly, another requirement is that all food "must be covered by clear plastic wrap". We have no idea what to read into that. (Pic: Getty)
