MEGAN McKenna shouted "shut the f*** up!" as she was asked to reanact one of her famous rages on Celebrity Juice.
The X Factor: Celebrity star was pushed to show off her angry face as Keith Lemon, insisted she "show off uncontrollable rage".
Megan struggled at first, telling the host to "f*** off" after he called her attempt "rubbish".
But she quickly found her stride as she screamed "shut the f*** up" with a scowl.
It got huge cheers from the crowd, as well as her teammates Mel B and McFly.
Megan got the reputation for having temper tantrums during her stints on I'm A Celebrity , Ex On The Beach and Towie.
The 26-year-old's fiery outbursts always amused viewers - especially the jaw-dropping moment she was temporarily removed from the CBB house by security.
But she's put all the behind her now after saying goodbye to her chequred past in search of a fresh start.
That was until Keith Lemon brought it all up again on Celebrity Juice tonight.
With hopes of being crowned champion of The X Factor: Celebrity, Megan has ditched her famous trout pout so she can be taken seriously as a country singer.
She told The Sun's Fabulous: “I’m a completely different person these days.
“I’ve done so much growing up. I know people see me as Mental Megs – if I’d watched me, I’d think: ‘Oh god, I don’t like her.’
"But the truth is I was just a broken, upset young girl and I didn’t really know what I was getting myself into.
“When I came out of Big Brother and saw it all back, I was like: ‘Oh my god, my mouth! My nan’s going to kill me.’
"I just can’t behave like that. I’d be trying to express myself, but it would come out all wrong.”
Now she's focused on making it as a pop/country singer - and has more than impressed The X Factor judges Simon Cowell, Nicole Scherzinger and Louis Walsh.
