John & Edward reportedly planned to invade the stage at T4's 'Stars Of 2009' while Calvin Harris was performing last weekend.
The Irish twins allegedly wanted to take revenge on Harris after he stormed the stage with a pineapple on his head during their rendition of 'Under Pressure' on November 14.
According to The Sun, the duo's plans were halted backstage at the event in London's Earls Court.
John & Edward were the seventh act eliminated from the ITV1 show and are reportedly in talks to launch their own books and fashion line.
Harris has since been given a lifetime ban from visiting The X Factor studio by the show's producers.
The X Factor continues on Saturday at 8pm on ITV1.
