After the magazine mogul passed away at his beloved Playboy Mansion surrounded by loved ones on Wednesday, Hefner's daughter Christie Hefner and sons David Hefner, Marston Hefner and Cooper Hefner gathered for dinner at Katsuya in Brentwood on Thursday.
The gathering reportedly included a toast, presumably in honor of the late mogul. At one point in the night, the four siblings were spotted standing outside together and later got into a car together.
Hefner had Christie and David with his first wife, Millie Williams and sons Marston and Cooper with his second wife, Kimberley Conrad. Christie worked in the family's company, serving as Playboy Enterprises Chairman and Chief Executive Officer from 1988 to January 2009. Meanwhile, Cooper recently took over for his father as Chief Creative Officer.
