Wednesday night's Britain's Got Talent kicked off with an apology about Tuesday's show, from hosts Ant McPartlin and Declan Donnelly.The duo brought viewers' attention back to some swearing that happened the previous night, with Ant identifying the guilty party. New judge Bruno Tonioli was mortified as he realised that he had been caught out and as he was exposed, boos could be heard from the live audience. On Tuesday night viewers at home could hear Bruno, 67, appear to say: "F***ing hell" during the second live semi-final of the series.
