Kelly died in her sleep late Wednesday night while at a rehab facility in California. The actress's agent said she had checked in voluntarily to try to clean herself up, reportedly from alcohol problems.

The 43-year-old had been fighting her addiction for a while, and this wasn't her first time in rehab. She had also been arrested four times in the last three years for different offenses, including driving under the influence and assault.

Kelly was married only last October, to Robert Gilliam, but filed for divorce in July. The relationship was full of problems from the very beginning, and both sides had been accused of spousal abuse.
