The pair, who are rarely photographed together, made headlines Monday because of Ray's uncanny similarities to his father at the same age.
In addition to inheriting his father's looks, Ray, 22, is following in Nicholson's footsteps when it comes to a career in show business. Ray has already served as assistant director on two films and had a small cameo in the 2006 flick The Benchwarmers.
Ray is Nicholson's second son with actress Rebecca Broussard. The pair also had a daughter, Lorraine, who was born two years before. The Terms of Endearment actor has two other children with two different woman: Jennifer from his marriage to Sandra Knight and Honey Hollmann from his relationship to Danish model Winnie Hollman. Actress Susan Anspach claims her son Caleb Goddard was fathered by Nicholson.
Other celebrities in attendance at the Hampton's event included Sir Paul McCartney, Barbra Streisand, James Brolin, Robert De Niro, Sting, Gladys Knight and Jon Bon Jovi.
