Liza Minnelli has entered a "self-help" program at a drug and alcohol rehabilitation center in rural central Pennsylvania, her publicist said.
Minnelli's visit to the Caron Foundation, set in a former resort hotel in bucolic Wernersville, is routine, Warren Cowan & Associates said in a written statement.
"Liza Minnelli is currently doing her annual self-help program at the Caron Foundation, which she does eight weeks out of the year as part of her recovery," the firm said. "She is fine and she will continue her concert tour and all of her commitments as promised. She is in great condition."
Minnelli, 57, has spoken openly about being addicted to alcohol and painkillers and about her past stints in rehabilitation programs.
