After Will Ferrell’s Anchorman persona, Ron Burgundy, lovingly roasted Justin Bieber at his Comedy Central special this past March, the singer has returned the favor with his Halloween costume.

The Biebs posted a pic on Instagram of his holiday get-up, saluting Ferrell’s Semi-Pro character, Jackie Moon. Rocking a bright orange Afro wig, headband and teeny basketball shorts, JB was a spitting image of the unfiltered basketball coach from the 2008 comedy.

The 21-year-old crooner has been a hashtag magnet this past week after releasing the lyric video for his apologetic single “Sorry” and attempting to make his best Robert de Niro face during an interview with puppets. Expect more Bieber fanfare before his upcoming album Purpose drops Nov. 13.
