The pair, who haven't got on since day one, first began arguing after Jim asked Luisa Zissman whether she missed having a man in her life.
Linda asked Jim why Luisa would need in a man around, before later describing him as a "misogamist" to her fellow female housemates.
Jim also stood in the garden and yelled: "She's f***ing off her head - you're off your head you f***ing loopy b*tch!"
Later, the row escalated further when Jim suggested that their dislike of each other stemmed back to something "that happened in Frank Carson's dressing room".
Apparently this comment references Linda's late-husband Brian, and it sparked fireworks - eventually resulting in Linda sobbing under her duvet.
"My husband is dead, he's been dead since 2007 and he brings up something from the past," she fumed. "Jim is a f***ing a*sehole and has just proved to everyone what an a*sehole he is!"
Watching from home, furious Coleen - who appeared in CBB in 2011 - blasted on Twitter: "Can't speak cos I'm ready to scream! I could say so much, but I won't go to his level!!! So proud of my sis!! Xxx" Coleen tweeted.

One follower, however, replied: "tbf she has been pushing him all week he was bound to say something at some point, majority of country seem to agree."
But Coleen shot back: "Why doesn't he man up then and argue? He walks out every time then makes snide comments!!"
