"Robin Thicke & Miley Cyrus," the 87-year-old Playboy founder wrote via Twitter while sharing a selfie with Harris in his Los Angeles home.
Hefner wore a black and white striped top similar to Thicke while Harris, 27, wore her blond locks in two top knots, which is one of Cyrus' favourite hairstyles.
Harris is seen holding a red foam finger similar to the one that Cyrus used during her raunchy performance that invited lot of backlash.
