Liza Minnelli's reps confirm that the singer has checked into a treatment center in Malibu, California.
According to reports, 69-year-old Minnelli is seeking help for an addiction to alcohol and has already been at the rehab facility for a few days.
"Liza used to have a live-in sober companion years ago when she lived in New York," an insider tells RadarOnline.com exclusively. "And while she's continued to stay close to good influences out in L.A., she wasn't focusing as much full-time on her sobriety in recent months."
The daughter of Judy Garland — the iconic actress who died of an overdose of barbiturates in 1969 — last asked for professional help to battle her demons in 2004.
"She just needed to reset and everyone around her is confident she'll be back on track soon," the insider tells Radar.
