Beyonce Demands: Red Toilet Paper, Titanium Straws and More! >>Hollywood

Kendra Spears is engaged to a prince and will soon become royalty.

But Beyonce already is royalty and - according to a report in The Daily Star - she therefore has a few demands while performing the Mrs. Carter Show abroad.

A source tells that publication that Beyonce is "extremely regimented and is taking everything extremely seriously, so she expects her list of demands to be adhered to."

Among those alleged demands:

• No junk food.
• Her crew can only wear clothes made 100% from cotton.
• The use of titanium straws to drink a special alkaline water served at exactly 21 degrees.
• Red toilet paper.
• Freshly painted white walls in her dressing room. Also, a new toilet seat.
• The salad bar must only be comprised of green items.

Beyonce is performing this week in London at
