The X Factor got dangerous when pals Lisa Parker and Abbey Johnston took to the stage earlier this year.

The pair showed up to the Birmingham auditions and sang Don’t Stop Believin’ by Journey and Shayne Ward’s That’s My Goal. Their renditions were so bad that Simon Cowell branded it “the worst audition in history”.

Before turning on each other, the duo went on to upset fellow judges Louis Walsh and Natalie Imbruglia. Lisa told Louis

“Abbey fancies you but you’re old enough to be my grandad.”

They then launched an attack on Australian popstar Natalie shouting:

“Who are you?”

When the panel refused to put them through to bootcamp, Abbey turned to Lisa and punched her square in the face.

“All of a sudden I felt ­something across my head,” Lisa told The Mirror.

“I just remember being hit and then having a headache. I think Abbey only hit me once but then a security guard grabbed her and another one pushed me against the wall so I couldn’t get to her.”

“If Simon hadn’t been so nasty this probably wouldn’t have happened.”

However Abbey has defended herself, saying that Lisa lied about her feelings for Louis Walsh. She added:

Lisa’s a liar, it’s all her fault. If it wasn’t for me she would never have been allowed on stage to even see Simon. It’s sad but stuff happens.”

An X Factor spokesman said: “Things got a bit heated. Producers quickly stepped in.”

Watch Lisa and Abbey get physical on tomorrow night’s X Factor show. Perhaps they would have been better singing ‘Hit me Baby One More Time.’
