Britain's Got Talent fans call for 'loose cannon' Bruno Tonioli to be replaced over 'potty mouth' as he swears again

Britain's Got Talent judge Bruno Tonioli made an apology live on tonight's live semi-final after he swore for a second time. The show newcomer, who replaced David Walliams this series, said a heartfelt sorry after he slipped up again in the live semi-finals.
