X Factor twins John and Edward Grimes were forced to call off their attempt at the world’s loudest scream, after too few fans showed up to make it possible.

The boys were planning to make their attempt at the Guinness World Record during their opening of an indoor funfair at Birmingham’s NEC.

The current record is 129 decibels and after singing a few songs for the crowd, the twins were informed that there weren’t enough people there to break it. That X Factor fame sure does fade quickly doesn’t it?
