Hugh Hefner and his wife Crystal Harris celebrated early Halloween at the Playboy mansion's annual costume party, dressing up as this year's MTV Video Music Awards' infamous duo, Miley Cyrus and Robin Thicke.

The 82-year-old Playboy founder and his 27-year-old wife indeed went all out mimicking 36-year-old married man Thicke and scantily-clad Cyrus, 20, disregarding their age gap. They wore almost identical attire that the singers wore at the memorable performance.

Hugh Hefner took Twitter to post up a selfie with Harris before the party started. Then, it followed with a shot of his wife twerking on him with her tongue out with a caption following, "Robin Thicke & Miley Cyrus." The magazine mogul sported a black-and-white striped suit, which actually appeared to be a prison uniform, looking closely at it. He completed the costume with a pair of black aviators and a gold chain.

Crystal Harris also posted up some photos of herself and Hefner on Instagram, showing off their costumes, which she captioned, "#robinthicke #mileycyrus." The former Playboy model tried to imitate Cyrus' nude get-up, which the singer wore latex two-piece at the VMA show. Harris covered up a bit more than the singer, wearing a nude spaghetti-strap tight mini-dress. She accessorized her Miley Cyrus look with her blonde hair in two high buns, a pair of sparkly black sneakers and of course, can't forget about the foam finger.

The couple certainly had an awesome time dressing up. "I had so much fun dressing as Miley Cyrus!" Crystal Harris shared her excitement on her Instagram.

Harris was not the only one who was inspired by Cyrus for Halloween. Paris Hilton also attended the same Playboy party wearing another version of Miley Cyrus' costume - the gray teddy bear onesie from Cyrus' twerking video on YouTube. It seems that we can definitely expect to see several Miley Cyruses walking around in the street on this year's Halloween.
