33. Diana Ross
The great Diana Ross is known around town to be a bit difficult, but she should be. She's Diana Ross. She's been slapped with an extreme DUI when her blood alcohol content was nearly over triple Arizona's .08 maximum, earning her two days in jail. Most recently, Ross threw a tantrum in a L.A. restaurant when they wouldn't seat her as she waited for her daughter to arrive. Instead, Ross sat herself. The manager then had to tell her that she wouldn't be served if she remained, and Ross refused to move.
