Ant and Dec were forced to apologise to viewers at home during Sunday night's Britain's Got Talent final as an act was heard swearing.
Across the past week, acts have battled it out in five live semi-finals - with five acts put through after receiving the most audience votes and the other five voted through by the judges.
However, during Viggo Venn's act on Britain's Got Talent, viewers heard him say "Oh s***" as his performance appeared to go wrong. Ant and Dec then proceeded to remind Viggo he was live on television.
