Security at the Dancing On ice studios in Borehamwood will be tripled this weekend after it was announced One Direction will be performing their new song on the show.
It was revealed on last night's live results that the former X Factor finalists will be singing their new song One Thing on Sunday, as the remaining celebs skate to classic pop tricks.
As a result, bosses are reportedly drafting in extra resources to help control the huge crowds expected to gather in the hope of seeing the boys.
"Producers are very concerned that thousands of fans will storm the studios," a source told The Sun.
The insider added: "That cannot be allowed to happen during a live show."
Dancing On Ice 2012 continues at 6:25PM on ITV1 this Sunday.
