LOS ANGELES - A spokeswoman for Demi Moore says the actress is seeking professional help to treat her exhaustion and improve her health, but other reports claim the treatment is for suspected substance abuse.
Publicist Carrie Gordon says the decision is due to the stresses in Moore's life, and she looks forward to getting well.
Gordon did not release any other details about the nature or location of Moore's treatment.
Her daughter, Rumer Willis, was seen pacing and smoking outside the hospital in these photos.
TMZ.com said paramedics responded to Demi's L.A. home after a friend called 911 Monday night.
After paramedics assessed her for a half hour, the actress was reportedly transported to a local hospital.
TMZ said Demi was doing whip-its, a street name for a type of nitrous oxide. Her friend reportedly said she became upset when Demi had a reaction and lapsed into semi-consciousness.
The online site also said Moore has dropped out of her upcoming movie, "Lovelace."
The past few months have been rocky for Moore. She released a statement in November announcing she had decided to end her marriage to Ashton Kutcher following news of alleged infidelity. The two were known to publicly share their affection for one another via Twitter.
Moore still has a Twitter account under the name mrskutcher but has not posted any messages since Jan. 7.
