ITV2's The Big Reunion has seen the likes of 5ive, Liberty X and B*Witched reform for the series, and next week's episode will focus on Liverpudlian girl group Atomic Kitten.

Speaking about one particular fight that happened between members Liz McClarnon and Natasha Hamilton after a G-A-Y concert, the ladies explained that tensions were so high things often got out of control: "It got more and more angry to a point where we were literally screaming at each other."

McClarnon added: "She just launched at me. You know when you go, 'What the hell just happened?'"

McClarnon also confessed to hitting Kerry Katona after she brought her boyfriend, Brian McFadden from Westlife, on tour which meant there was no room for McClarnon's brother in the car: "I didn't know she (Kerry) was bringing Brian with her for the day, I'd cleared it with the tour manager that I could bring my little brother."

"As Brian was already in the car the main thing was that Joe was not going to be able to get in the car so that really, really, really annoyed me... I hit her."

Katona then admitted how that argument ruined her relationship with McClarnon: "Well that was it. I undid my seatbelt, I've gone for her. I kicked her out the car. I said, 'Drive off'. I left her in the street. I was screaming, I was so angry. [After that] I used to make her get changed in the toilets. On stage, I'd stamp on her foot."
