"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. She looks forward to getting well and is grateful for the support of her family and friends," Moore's spokeswoman said in a statement to Reuters.

The statement follows media reports that Moore was rushed to hospital on Monday night after paramedics were called to her Los Angeles home. Celebrity news website TMZ.com cited substance abuse as the cause, but that could not be confirmed.

Moore's representatives declined any further comment beyond the written statement.

"Ghost" star Moore, 49, filed for divorce from 33-year-old "Two and A Half Men" actor Kutcher in November 2011, after a San Diego woman went public about a brief fling she had with Kutcher.
