It all kicks off when some of the housemates make a mess in the house with sun cream. Chanelle and Isabelle play a prank on the house by putting ketchup and sun tan lotion on the floor in the kitchen.
Chanelle is called to the diary room and ordered to clean it up.
Lotan isn't happy and confronts the culprits in the bedroom and from there things get very heated
After being accused of dirtying up the house, Chanelle pointed out last night's chocolate fight: "Did anyone have a go when there was chocolate everywhere?"
"It's one for one and it's another rule for other. It is, it's bulls**t," she snapped.
As Lotan argued back, Chanelle concluded: "Get out the f**king room then you ****."
Lotan retorted: "Oh, she has to be vile because she's got not f**king vocabulary."
This set Chanelle off as she raged: "Alright so you're going to mock my f**king intelligence alright. "
"Your intelligence is your problem, not mine," Lotan remarked.
Chanelle and Lotan's argument then descended into a huge shouting match that probably woke up most of the residents in Borehamwood.
Chanelle continued to rant at Lotan: "Oh p*** off, just f**k off. Get him out of here. F**k off then, I'm not arguing, MOVE."
As Lotan insisted he had 'nothing more to say', Chanelle went on: "Get the f**k out my face. Irrelevant, IRRELEVANT. MOVE. You f**king beg, f**k off you beg, you attention seeking beg."
The row soon woke up some of the other housemates who rushed to see what was going down, as Savannah and Hannah escorted Lotan away from a fuming Chanelle.
