Britney is off her personality-dulling meds and maybe enjoying a mild manic episode in a great mood this Halloween!

The pop princess recites the Vincent Price monologue from Michael Jackson’s “Thriller” in a campy new promo for BBC’s The Radio 1 Breakfast Show With Nick Grimshaw.

Yep, bringing out the best in Brit is gay DJ Nick Grimshaw, who's just mates with One Direction's Harry Styles!

You better work, witch, below.
