JO Brand had viewers at home in stitches as she appeared in the latest celebrity edition of Who Wants To Be A Millionaire.
The comedy star was one of the latest in a string of celebs to take part in the ITV game show fronted by Jeremy Clarkson.
During her appearance on the show, Jo gave away a little bit too much information that had viewers roaring with laughter at their TV sets.
During the quiz, Jeremy asked Jo: "The film 'The Social Network' tells the story of the creation of which website?"
Jo unfortunately suffered a mind blank which left her struggling to answer the movie question.
As a result, the comedian decided to use one of her lifelines and ask Jeremy for his advice on the question.

Jo mulled over the possible answers as she sought Jeremy’s advice and he was quick to offer up his personal thoughts.
The TV presenter said confidently: "Here's what I think. Actually I don't think, I know it's Facebook."
Jo appeared to relax as she told Jeremy: "I thought as much," insinuating she did have an inkling toward the answer.
However it was what the actress said next that left Jeremy blushing and viewers at home in hysterics.

The star mused: "I just had a little wobble and almost wet myself, so I thought I'd better ask you."
Jeremy re-affirmed that Facebook was his final answer as Jo agreed with him and selected that as her choice.
Fans at home were loving Jo as they shared their opinions on Twitter.
One fan adoringly said: "I love Jo Brand, she’s so funny #whowantstobeamillionaire."
Another wrote: "Love Jo Brand she is hilarious."
One fan was however left shocked that the star was not even more sure of the answer, as they said: "Wait...Jo Brand hasn't heard of The Social Network? It's one of the most iconic modern movies! That's like not knowing James Cameron directed Titanic. #WhoWantsToBeAMillionaire.”
Jo managed to bag her charity a worthy £64,000 during her time on the show.
Elsewhere in the episode, journalist Dan Walker left viewers stunned at home over his lack of general knowledge.
At one point, Dan, 45, was asked: "The Royal residence Sandringham House is closest to which of these cities?" and his options were Brighton, Bristol, Norwich or York.
Despite being a national TV journalist and reporting from all over the country during his career, Dan didn't know, and when Jeremy said he thought Dan would have covered plenty of stories from there, Dan replied: "I've never been to Sandringham."
