Kayleigh Morris EXPLODED at "f**king weirdo" Arthur Fulford in the Big Brother 2017 house last night.
The pair locked horns following the latest live show, although it's not entirely clear what exactly sparked the row.
In a clip that aired on Big Brother's Bit On The Side, Kayleigh was seen raging at Arthur over an apparent incident following the first eviction.
"You're playing some silly little petty f**king game, f**k off," Kayleigh snapped.
Arthur hit back, accusing Kayleigh of 'not being a woman'.
"I've literally given my life to women, I've dedicated my life to women and I'll tell you right now, you're not a woman," he said. "There's no way women should ever act like you today."
Kayleigh spat: "You're a contradicting little c**t. F**k off out of my face before I go mad. F**k off out of my face before I go mad, f**k off, f**k off! Leave me the f**k alone!"
As the other housemates watched on, Kayleigh continued to rant: "You are playing some f**king silly game, you are a f**king weirdo. F**king weird."
"I actually liked you up until that second, you've f**king pissed me off and now I'll make your life in here a living hell. I can be a c**t."
Arthur then retreated to the bedroom but Kayleigh wasn't finished.
She continued shouting: "I'm not a woman? I have a f**king vagina!"
The full argument and fallout will air in tonight's Big Brother 2017 highlights show from 9PM on Channel 5.
Earlier yesterday the live show saw Mandy Longworth become the first housemate to be evicted from the series.
