The esteemed three-time Oscar winner has been absent from public view for more than a year, leading his friends to describe his current lifestyle as that of a hermit.
Various insiders have disclosed to RadarOnline that the 85-year-old Hollywood icon now rarely ventures outside his residence and there are growing worries about his mental state, with speculations of potential cognitive decline.
The father of five was last spotted attending a Los Angeles Lakers game at the Staples Center alongside his son Ray in October 2021.
Nicholson is said to predominantly confine himself within his lavish Beverly Mansion, a property he acquired from his late friend Marlon Brando for $5 million back in 2005.
The opulent 3,303-square-foot estate boasts four bedrooms, three bathrooms, and a private pool.
According to sources, Nicholson strongly asserts his home as his sanctuary, but many wish he would emerge and offer some reassurance about his well-being or simply interact with people.
While he maintains contact with certain family members, particularly his son Ray, whom he admires greatly, his days of socializing seem to be long gone, noted an insider, alluding to his diminishing interactions with the external world.
Concerns deepen among those close to the “One Flew Over the Cuckoo's Nest” star as they observe parallels between his reclusive tendencies and those of Brando, who passed away in 2004 after years of seclusion.
Reflecting on Brando's solitary final years, a source drew comparisons, emphasizing the limited connections Nicholson now has with the outside world, primarily through his children.
Observers lament that Nicholson appears to be evading reality, exhibiting a reluctance to engage with the world, which they find disheartening.
Nicholson's most recent on-screen endeavor was the 2011 romantic comedy “How Do You Know,” co-starring alongside Reese Witherspoon, Paul Rudd, and Owen Wilson.
In his personal life, Nicholson was wed to Sandra Knight for six years after marrying in 1962.
His most enduring romantic liaison was with actress Anjelica Huston, spanning from 1973 until their relationship dissolved in 1990.
Reports from 2021 indicated that Nicholson's son Ray and sister Lorraine have taken on responsibilities to oversee his well-being, with the close-knit Mulholland Drive community expressing concerns about his mental state despite his physical health being relatively stable.
Witnessing the decline of such a gifted actor like Jack Nicholson has left many saddened by this trajectory for the Hollywood icon.
It is known that Nicholson currently leads a solitary life as a bachelor, with no reports of any current romantic entanglements.
The Post has sought comments from Nicholson's representatives regarding these developments.
