Oti and Bill’s debut performance in the ballroom was a Cha Cha Cha to Pata Pata by Miriam Makeba.
The stars were awarded six points by judges Shirley Ballas and Motsi Mabuse, while Craig gave them a three.
Kevin thought Craig’s score was harsh, as he added: “For me, it was a really harsh mark, and maybe it was an assumption – he’s a comedian, therefore, he’s funny.”
Last week, Oti and Bill wowed the judges and viewers at home with their Doctor Dolittle-inspired Quickstep.
The couple scored an impressive 24 points after receiving an eight from Craig.
