Let the Miley Cyrus Halloween costumes begin! Hugh Hefner and his wife Crystal Harris sure got into the Halloween spirit Saturday night. Shortly before kicking off his annual Mansion Halloween party at the Playboy Mansion, Hefner shared a photo of himself and Harris dressed as Cyrus and Robin Thicke from their controversial 2013 Video Music Awards performance.

"Robin Thicke & Miley Cyrus," the 87-year-old Playboy founder wrote via Twitter on Oct. 26. Alongside the caption, Hefner shared a selfie with Harris in his Los Angeles home.

Hefner wore a black and white striped top just like the R&B crooner, while the Playboy model, 27, rocked her blonde locks in two top knots. Harris also is seen holding a red foam finger that the "Wrecking Ball" singer vigorously waved around between her legs and against Thicke during their Barclays Center set. Shortly after, Hefner also shared a picture of Harris "twerking" on him, as she stuck her tongue out.

Hefner and his stunning wife sure like to keep their marriage fun and fresh. The couple -- married since New Year's Eve 2013 -- were spotted in early September getting the VIP treatment while riding on motorized scooters in Disneyland with a group of friends.
