Hollywood icon Jack Nicholson has disappeared from public life, and pals of the actor are reportedly worried the end could be near.

The 84-year-old Batman star is currently living out his “sad last days” at his Beverly Hills, Calif. mansion, an insider spilled to Radar. The Shining star has reportedly owned the 4-bedroom, 2-bathroom, 3,300 square foot abode since the ‘70s.

The source dished his close pals’ fear he is suffering from Dementia. “Jack and I have been friends for years and he doesn’t leave his house anymore… I think his son and daughter are looking after him now,” the insider continued.

The three-time Oscar winner has five children, but was often snapped with his daughter Lorraine and son Ray near his home. “The Mulholland Drive community is pretty close-knit, and they are all worried about him. Physically he is fine — but his mind is gone,” the source added. “It’s really sad to see such a super talented actor, like Jack, go out this way.”

The last film Nicholson appeared in was the 2010 rom-com How Do You Know starring Reese Witherspoon and Owen Wilson.

Nicholson was forced to retire from acting in 2018. “There is a simple reason behind his decision — it’s memory loss,” an insider told the outlet at the time. “Jack has memory issues and can no longer remember the lines being asked of him.”

Despite quietly stepping away from Hollywood, the insider noted that the One Flew Over The Cuckoo’s Nest star had zero “intention of retiring from the limelight.”

The avid Los Angeles Lakers fan is “not retiring from public life, at all,” the source explained. “He just doesn’t want a tribute. He’s happy to tacitly join the retirees club like Sean Connery.”

Unfortunately with his health reportedly taking a turn for the worse, a pal close to the 12-time Academy Award nominee will most likely not be making his usual front-row appearance at Staples Center when the NBA season commences in October.

The Kennedy Center Honor recipient in 2001 reportedly has no upcoming movie projects in the works.
