Liza Minnelli is on the road to recovery.
The Cabaret star, 69, was seen out for dinner in West Hollywood over the weekend and has returned home from rehab, her rep confirms to PEOPLE.
The Oscar winner dined at The Real Housewives of Beverly Hills star Lisa Vanderpump‘s restaurant Pump on Sunday night, after which she greeted fans and signed autographs while looking happy and in good spirits. She wore an all-black ensemble and smiled for photographers.
The singer is also headed back to the stage. She is set to perform at the IP Casino Resort & Spa in Biloxi, Mississippi, on July 24.
Minnelli checked into a treatment facility last month for substance abuse, Scott Gorenstein, a spokesman for the performer, told PEOPLE.
“Considering she’s doing so well, we expect that she’ll be released shortly,” he said at the time.
The performer has battled substance abuse throughout her life. She was treated in 1984 for addiction to alcohol and prescription drug use, and in 2002, court documents revealed that alcohol allegedly played a role in her divorce from her fourth husband, David Gest.
