The network has yet to determine how the scene kept playing behind news presenter Sophie Raworth.
The woman whose topless body was seen in the background of a BBC News at 10 broadcast earlier this week has spoken out - and it's none other than Hollywood star Anna Paquin.
Before the truth was revealed, many viewers took to social media to question if a member of the BBC staff was watching a pornographic film.
The BBC employee was watching a season six episode of the Emmy-nominated TV series which saw Paquin's character in a sex scene with co-star Robert Kazinsky who played Warlow.
