Megan McKenna allegedly trashed ex Mike Thalassitis's flat during a blazing row and punched him in front of friends, according to reports about the reality couple's broken relationship.
Megan - whose raging temper tantrums have been well documented in TV shows she's appeared in - is accused of "smashing up" her Love Island ex's home during a stormy argument.
"It was nuts really. Mike and Megan had only been dating for a little bit, but they'd broken up a few times," a source told OK! Online .
"We were all back at his place having a drink and she just went off. None of us were surprised they were arguing because we'd seen them arguing loads in the past over stupid things.
"But this time she was going off and Mike kept telling her to chill out and calm down, but she properly lost it and smashed up his flat screen TV and a lot of his things in his apartment and repeatedly punched him."
The witness went on: "She was like a hurricane, tossing things around and throwing s**t.
"To be honest the violence and fury was quite surprising because we'd only seen that happen on TV before, like when she used to go nuts at Pete Wicks on TOWIE.
"But to see her go from zero to 100 was mad. I can't actually remember what the argument was over, but Mike was devastated and embarrassed. We all felt sorry for him and told him he needed to end that relationship.
"But actually I think they may have broken up that night and then got back together again after it, before breaking up again for good."
TOWIE star Megan, 26, allegedly also told Mike she would "ruin him and end his career".
