A second series has been commissioned for this Autumn.
The series sees the nation's favourite comics and celebrities are competing to convince Mel that they are the most Unforgivable person in the room.
To do this they will have to dredge up their most outrageous sins, lies, legal transgressions and morally bankrupt behaviour. In each episode three celebrities are coming clean and regaling tales of their most despicable deeds and uncharitable behaviour as they are probed by host Mel Giedroyc and her assistant Lou Sanders for all the dastardly details.
Speaking on ITV's Lorraine on Thursday morning, Mel said: "I'm so pleased because we had a lot of fun making that show. We're going to make some more, fingers crossed at the end of June, beginning of July. So hopefully some time around the beginning of autumn that will be back on Dave.
She continued: "It's great, great fun, naughty show, you must come on Lorraine - I want to hear your secrets."
Mel Giedroyc: Unforgivable is available now on UKTV Play.
