Texas star Sharleen Spiteri was left furious with Whitney Houston after performing at the same show as the singer - because the superstar made her entourage carry her down a flight of stairs.
The Scottish rocker was shocked after spotting the I Will Always Love You hitmaker being hauled down a stairwell at an awards bash.
And she was so angered by Houston's behaviour, she felt like "slapping" the singer for her demanding antics.
Spiteri tells Britain's Gay Times, "(The word diva is) just another way of saying c**t. I remember performing at an awards ceremony with Whitney Houston, and she had to be carried down a flight of stairs. People like that deserve to be slapped. I'm all for a little bit of slapping when there's a really bad attitude. That kind of attitude is just bad manners. Some people confuse a bad attitude with bad manners, but bad manners are just a whole different ball game. You should be, if possible, locked in a cupboard or something. Taught a lesson until you're begging to come out."
