In what could be the jaw-drop moment of the series, Sue Perkins discovers that there's another kind of heat in Agnes Brown's kitchen in All Round to Mrs Brown's on Saturday night.
While the former Great British Bake Off presenter is having a yap with Finglas' most famous mammy, she is introduced to Agnes' best pal Winnie, who is somewhat starstruck.
As Winnie heads out the door, her goodbye to Sue doesn't quite go as planned - with the faux pas bringing the house down.

As Agnes, Winnie and Sue try to regain their composure, the presenter says: "This is a very different show from the one I thought it was going to be!"
"In for a penny!" she continues. "Such a refreshing change from a drink!"
Also joining the fun on Saturday night are dancer Ashley Banjo and his mammy; former JLS singer Aston Merrygold and Silent Witness star Emilia Fox.
