Karen and Sharon

Karen is Sharon's maternal half sister. Karen is a plus size model from the U.K who travels around the world. Her appearance is similar to Sharon’s; she has short red hair, is short and overweight. She appears to be somewhat of a spoilt princess and takes an instant dislike to Sharon, however befriends Kim upon their meeting.

Karen is portrayed by Matt Lucas and makes her first appearance in the season 4 episode “Roots”. She also appears (albeit in a video message) in the series finale “Wedding of the Century”.
