Hollywood and business mogul Steve Bing died by suicide following a yearslong battle with depression and financial woes after blowing much of his $600 million fortune, friends said.

Bing, 55, died after jumping from his 27th-floor apartment in LA’s Century City on Monday. He was a notable philanthropist and Hollywood investor, including as a producer for the Sylvester Stallone remake “Get Carter.”

Bing dropped out of Stanford after receiving a $600 million inheritance from his grandfather, a real estate developer. He is perhaps best known for being the father of Elizabeth Hurley’s son, Damian, born in 2002.

Bing initially denied he was his father, but a DNA test proved otherwise.

While the Hollywood community remains shaken by his death, those close to Bing say his jet-set life was enviable on the surface — with close friendships with President Bill Clinton and billionaire Ron Burkle and relationships with a host of beautiful women — but in reality he was very troubled.

One friend, who asked not to be named, said, “Steve was the most charming, caring and generous guy you could ever meet. Yes, he liked beautiful women, but it never worked out. He has gone through a dark time for years. He talked about battling mental illness, bipolar disorder. His close friends are devastated about his death but, sadly, not surprised.”
