Following her brief stint in the hospital last month, Demi Moore is now in rehab, according to E! News. The 49-year-old actress reportedly entered Cirque Lodge addiction treatment center in Utah the week after her January 23 hospitalization in California.

Moore reportedly is receiving treatment for what E! News describes as "an eating disorder and addiction issues." A source said, "She's on total lockdown and only talking to a small group of people."

After Moore was hospitalized, her rep said the actress was seeking treatment for exhaustion. However, a recording of the 911 call placed before Moore was taken to the hospital indicated that she'd been "smoking something" and had experienced seizure-like symptoms.

Moore's exes Ashton Kutcher and Bruce Willis were both spotted at her California home last week, but E! said she was not there due to her ongoing stay in rehab.

Cirque Lodge has treated many other celebrities in the past, including Lindsay Lohan and Eva Mendes. A rep for Moore declined ABCNews.com's request for comment.
