In 1996, Mueller was arrested on DUI charges in Palm Beach County, Florida. In March 2001, she was arrested in Miami-Dade County, Florida for cocaine possession. In July 2011, Mueller completed an outpatient rehab program. In May 2013, officials from Department of Children and Family Services removed Mueller's then 4-year-old children from her care, when her suspected ongoing drug use made the house unsafe for them. Mueller entered a rehab program soon after, while her sons were initially placed in the care of Denise Richards, Sheen's second ex-wife, and later transferred to the care of Mueller's brother Scott. In December 2014, full custody of her then 5-year-old sons was returned to Mueller by the court. Mueller walked barefoot into a bar with her sons and a nanny on the morning of November 16, 2016 and was taken to a hospital for evaluation.
