Famous across the Chatsworth Estate for her sexual skills, Karen is the daughter of agoraphobic Sheila.
Karen is also famous for sleeping with Frank while he was dating her mother and she was dating Frank's son Lip.
The arrival of Jamie Maguire tamed Karen's wild ways and she eventually married into the feared family, but only after she endured some severe psychological torture from Maguire matriarch, Mimi.
Karen works in Chatsworth local The Jockey and is every inch the reformed slapper.
During Series 6, she and Jamie went through a bit of a rough patch and split up, but they got back together in the end and are now proud parents.
So all's fine and dandy - until Series 7 when her affair with Joe Pritchard (one-time boyfriend of her sister-in-law) triggers some mental health issues.
Tough as old boots though, Karen gets herself back on her feet. For a while she thinks Joe's the man for her.
Coming to her senses a little too late, Karen's left hoping Jamie will take her and Conor back in Series 8.
