Following their previous clash in last night's highlights show, this evening the girls come to blows again
In the bedroom, Chanelle slams Simone: "You are playing a game, you're s**t stirring."
Simone replies: "Why are you still going on about it Chanelle?"
Chanelle continues going on about it: "No one's trying to turn the house against you."
Simone insists: "It looks like you are Chanelle, by making lies up about me."
Chanelle snaps: "Get out of the room!"
Chanelle then complains: "She's dangerous, she's not right in the head."
Meanwhile, Simone breaks down in tears during a chat with Deborah: "I am trying so hard, you don't understand."
Elsewhere on Big Brother tonight, a beauty pageant task gets super bitchy.
Yesterday in the house, Big Brother gathered the group at the sofas to reveal all about the new challenge.
Big Brother announced: "Today, some of Big Brother's glamorous, strong and fierce females will compete for the title of BB Queen in Big Brother's very own pageant contest."
Competing were the same familiar faces, with Chanelle representing Manchester, Ellie her home town of Castleford and Deborah East London.
Meanwhile, on the judges desk were Hannah, Kieran and Sue.
Chanelle, Ellie and Deborah each had to take to a stage in the garden to perform in numerous rounds. As well as showing off their runway walk, they had to demonstrate an impressive talent to the judges.
Things turned ugly with Sue branding Chanelle's performance pantomime with her reacting: "You can shove your crown up your a***s."
The task and fallout will air in tonight's Big Brother 2017 highlights show from 9PM on Channel 5.
