Claudia Winkleman was forced to apologise last night after footage of her swearing was accidentally broadcast at the beginning of her Film 2010 show.
As the programme started, viewers heard a four-letter-word rant which was apparently down to a technical difficulty.
The presenter, 38, who co-hosts the show with film critic Danny Leigh, apologised twice during the show.
Winkleman told viewers “'Before we review this film can I just say I'm really sorry, because I think there was a technical difficulty at the top of the show and you might have heard stuff and I apologise if there was. If you didn't, just ignore what I just said."
Claudia took over presenting the show from Jonathan Ross after he resigned from the BBC following the Sachsgate scandal, making her debut a month ago.
