Sad Last Days: 'Desperate' & 'Broke' Liza Minnelli In Hiding — Will She Sing Again?

After decades of starring in movies and on Broadway, friends fear that Liza Minnelli has gone broke and might be facing her sad last days, RadarOnline.com has exclusively learned.

The iconic song-and-dance gal has become a virtual recluse since moving from New York to a rented L.A. home last September, and is so hard up for cash she's selling her famed Andy Warhol art collection for $40 million — far less than what it's worth, it's claimed.

"It just sounds like she's desperate," one long-time insider told Radar. "There's a lot going on around her, and none of it is very good. You just have to wonder if she needs the money."

Added another source: "She's in bad shape, and we might never see her in public again. She doesn't want to be seen by fans and has locked herself away in a private house in Los Angeles."

The 70-year-old Oscar winner for 1972's Cabaret and daughter of movie legend Judy Garland has visibly deteriorated in the past few years.

She's waged a grim battle with drugs and booze her entire life and has also suffered a slew of health problems. Now, an insider claimed she's fallen off the wagon and is back to her old abusive habits.

While a rep insists everything is fine, friends fear the superstar is facing her sad last days.

"I hope it's not true," an insider said. "I hope the money from the art sale helps her and I hope she gets back on her feet."
