Wearing a black tank top and black hat, the Canadian singer mooned the camera standing in front of a Justin Bieber poster. The 18-year-old Bieber quickly deleted the post, which had already received 86,000 likes, according to Access Hollywood.
Bieber's manager, Scooter Braun, tweeted supportively about the incident:
