WATCH: Adele Slays 'Monster'—Nicki Minaj Approves

As I'm sure you are aware, Nicki Minaj's guest verse on "Monster" is the best female guest verse of all time--top 5 overall. And Adele knows it like the back of her best Grammy-snatching hand.

On The Late Late Show with James Corden, Adele climbed into the passenger seat for some carpool karaoke. She sang some of her old hits, even busted out a little Spice Girls "Wannabe":

But then things took a real turn. Into incredible. She goes from her gorgeous balladry to dropping F-bombs like old Buns Minaj herself.

Nicki--who is openly not easily impressed--gave Ms. Adkins her tens:

Pull thru, QUEEN!!!!! #Adele #Monster the attitude & fingers to match. #Oh #Ok #IcoNic I cried when she waved bye to the careers #Hello #BuhBye
