Biography

Johnson's mother revealed that her daughter struggled with borderline personality disorder. Johnson's mother attributed her daughter's troubles to the disorder.

In 2006, Johnson had a public falling out with her aunt, Elizabeth Ross "Libet" Johnson, after Johnson accused her aunt of stealing her boyfriend, John Dee.

In 2007, Johnson adopted Ava Monroe (born August 14, 2006), an infant girl from Kazakhstan. Nicky Hilton is the child's godmother.

Johnson was openly bisexual and dated both men and women. In October 2009, Courtenay Semel, whom Johnson had dated off and on from 2008 to 2009, reportedly set Johnson's hair on fire after a fight. In November 2009, Johnson was arrested for allegedly stealing jewelry, shoes, six hundred pages of a legal document, clothing, and underwear from the apartment of English fashion model Jasmine Lennard, who was tipped off by Semel. Johnson pled not guilty to burglary and receiving stolen property and had a preliminary hearing scheduled for February 2, 2010.

After refusing to seek treatment for drug abuse, Johnson was cut off financially by her family, which led to the impounding of her Porsche, for which court records showed Johnson owed Porsche Financial Services a total of $105,740.93. Johnson was also sued by a nanny service who won a $20,000 judgement against her.

On December 9, 2009, Johnson announced via Ustream video that she and reality television star Tila Tequila were engaged. Four days later, Johnson stated that she would be changing her and her daughter's last name to "Nguyen", Tila Tequila's legal surname, though this never occurred.
