Shania Twain, 50, is now having her Rock the Country tour on North America and those places that she will cross need to be ready.

She just became one of those superstars who insist on getting diva treatment during her tour. The actress makes sure that her personal assistant will inspect the venue 24 hours before her arrival.

Shania expects seven humidifiers during her stay in a hotel. Also candles must be in her suite, it must be made either from soy, vegetable or beeswax or any other naturally scented or citrus, lavender and grapefruit.

The 'That Don't Impress Me Much' performer prefers to have three bouquets of white or cream roses instead of any other flowers. Lilies, baby's breath or other 'filler' plants in the vases are a 'big no no'.

The country hit maker is an ovo-lacto vegetarian which means she doesn't, consume meat, poultry or fish  but takes eggs and dairy in her diet. She requested to choose from six meal options for her lunch and dinner if she wants room service to serve food to her suite.

Because of illness, Shania's couple of concerts in the week was all cancelled. Her New York and New Hampshire concerts were one of those concerts that have been cancelled.

Cancelation of her concerts resulted after doctors diagnosed her to have respiratory infection and she needed to rest for a couple of days.

One of the famous divas who also demand diva treatment is Mariah Carey who requests Cristal champagne, an assistant to set out of her chewing gum and bottles of vitamin water to bathe her dogs in. Also another one of them divas is Jennifer Lopez who requires her dressing room to be painted white and the whole thing inside has to be white too, from the flowers to the tablecloths, drapes, candles and couches.
