Mueller, Sheen's ex-wife, entered a facility Monday night seeking treatment for an addiction to Adderall. On Friday, Mueller was rushed to the hospital for a suspected overdose, but the mother of two originally insisted she had simply been deep asleep after making jewelry nonstop for several days. However, TMZ.com later reported that Mueller admitted that the incident was caused by taking too many Adderall pills.
Richards was also previously married to Sheen from 2002 until they filed for divorce in 2006. The couple has two daughters together.
