One Direction are being forced to spend £25,000 a DAY on security, it has been claimed.
The boys, who started their rise to fame on The X Factor in 2010, are currently in the US promoting their debut album.
But with an ever increasing fanbase, comes ever increasing security costs, with Harry, Zayn, Louis, Liam and Niall now having 20 bodyguards EACH to protect them!
"Having 100 minders on tour will cost at least £25,000 a day. It's astronomical - but the boys need the backup," a source said.
One Direction, who will be kicking off their US tour in May, revealed recently that UK fans were shy compared to the much more 'friendly' US teen fangirls.
The source added: "While they love the attention and the success, some situations have got a little out of control.
"A lot of the girls will stop at nothing to get them and its becoming quite scary."
