Megan, 23, launched into an alcohol-fuelled meltdown when EastEnders actor John complained about the lack of cleanliness in the house.
Taking it personally, Ex on the Beach star Megan raged: “It angers me in here that people do jack s***! I’m the fking one telling the truth in here cause everyone’s so scared to fking tell truth apart from me!
“It’s always John, ‘I’m the perfect one’. I f**king respect people in here, John.”
John, 44, managed to keep cool during Megan’s verbal attack, but she soon turned on US reality TV star Tiffany Pollard.
Referencing Tiffany’s own meltdown this week, Megan said: “I don’t know why you’re laughing, Tiffany; he’s the one who wanted everyone to walk out of this house for you! I stood up for you!”
While ex-Hollyoaks actress Stephanie Davis occupied the Diary Room, Megan continued on her rant around the house. Kristina Rihanoff, visibly shocked by Megan’s behaviour, said: “It’s like something possessed her.”
Eventually Megan was called to the Diary Room, where her anger continued. She fumed: “I’m not dealing with this sh*t anymore. I’ve kept it in all f**king day! I’m sick of it! I’m sick of the fakeness! He’s a liar. He slates Tiffany to the ground. You know what, there’s a few people who agree with me.”
With Megan’s temper reaching scary levels, Big Brother was forced to call security into the room to restrain her.
Although many viewers posted their concern and anger over Megan’s outburst some placed the blame with Big Brother, for starving the housemates during the latest task and supplying them with alcohol.
