This bitch is whack; can't stay out of trouble:

From Wikipedia,

Campbell has been accused and arrested because of committing acts of physical violence and verbal abuse against some of her employees and associates. She is often referred to in UK tabloids such as The Sun as Nutta because of her shocking public behaviour. Documented accusations include:

In 2000, she pleaded guilty in a Toronto court to a 1998 assault on Georgina Galanis, her then assistant; Campbell had assaulted Galanis with a telephone in a hotel room and threatened to throw her out of a moving car. Under an agreement with the prosecution her record was cleared in exchange for her expressing remorse; Campbell also paid Galanis an undisclosed amount of money and agreed to attend anger management lessons. [6]

March 2005, the model was said to have slapped assistant Amanda Brack and beaten her around the head with a BlackBerry hand-held personal organiser. The star's spokesman Rob Shuter denied the incident ever took place.

In July 2006, Brack began legal proceedings against Campbell, claiming the supermodel abused her verbally and physically on three continents. Brack accused Campbell of assault, battery, false imprisonment and infliction of emotional distress in incidents that started a month after she began working for her in February 2005 [7]
Italian actress Yvonne Scio has claimed the model left her "covered in blood" after a spat at a Rome hotel. Yvonne claimed: "She punched me in the face. She was like Mike Tyson." [8] Interestingly enough, Campbell once dated Mike Tyson.

On 30 March 2006 in New York City, Campbell was arrested for allegedly assaulting her housekeeper with a jewel-encrusted mobile phone, resulting in a bloody head that required several stitches.[9] She was charged with second degree assault,[9] a felony that carries a minimum sentence of one year and a maximum of seven years in prison.[10]

On 28 September 2006, she did not attend a required court appearance in New York City, and the judge ruled that he would order her arrest if she failed to turn up on court the following week, on charges of a second degree assault on her housekeeper, and could be jailed for up to seven years if convicted.[11]

On 25 October 2006, she was arrested in London on suspicion of assault. [1] She has been released on police bail.
On 14 November 2006, another former Campbell housekeeper, Gaby Gibson, began a new court case against the supermodel seeking unspecified damages, and accused her ex-employer of being a "violent super-bigot".[12]

On 16 January 2007, Campbell pleaded guilty to a charge of reckless assault against her maid Ana Scolavino. She was sentenced to five days community service and ordered to attend two days of an anger management course.[14]

According to a report on CNN, Campbell blames "her temper on lingering resentment toward her father for abandoning her as a child".[15]
