Grant has teased a possible exit from Celebrity Traitors after an extraordinary slip-up left the castle in confusion
The actor accidentally revealed his secret role before attempting to distract Rob Beckett with an intentionally ridiculous question
Their playful exchange continued in a new Instagram video, in which Grant appeared to hint that Thursday’s episode could bring his downfall
Viewers have praised the pair’s quick-fire humour, although many remain frustrated by the BBC series’ cliffhanger ending, which stopped before the celebrities completed their round-table vote.
