LOS ANGELES - Actress Demi Moore is being treated for "exhaustion," her publicist said Tuesday, after a media report said she had been rushed to hospital due to substance abuse.

Moore, who split from her younger husband Ashton Kutcher in November after reports he had been unfaithful, had been placed in a facility to receive treatment, the TMZ celebrity news website said.

It cited police as saying that a 911 call was placed late Monday evening. Paramedics responded to her Los Angeles home and, after checking her for half an hour, transported her to a local hospital.

"Because of the stresses in her life right now, Demi has chosen to seek professional assistance to treat her exhaustion and improve her overall health," said a statement issued by her publicist, Carrie Gordon.

"She looks forward to getting well and is grateful for the support of her family and friends," it added. The publicist did not immediately comment on the details reported by TMZ.

Moore, 49, and 33-year-old Kutcher announced their separation in November, after months of media reports about problems between the couple, who married in 2005. She had earlier been married to actor Bruce Willis for 13 years.

The actress made her name in movies including "Ghost" (1990), "A Few Good Men" (1992), "Indecent Proposal" (1993) and "G.I. Jane" (1997), as well as a 1991 Vogue magazine cover photo of her heavily pregnant.

Kutcher is best known for TV shows including "That 70s Show" and "Punk'd," and last year replaced troubled actor Charlie Sheen in the popular comedy "Two and a Half Men."
