One Direction have arguably one of the most loyal fan bases in the world right now, but it seems that some are more committed than others.
The boys' revealed that a group of let's just say 'spirited' ladies once chased after the band's car and exposed a little more of themselves than they were expecting.
One Direction were in Sweeden when the girls lifted up their tops and pressed their bare breasts against the windows of the bands' car.

Demonstrating the incident, Louis told Alan Carr on tonight's Chatty Man: "The Swedish fans were pressing their breasts up against the car window."
Wholesome Niall then added: "It was quite embarrassing."
We bet you loved it Niall!
The boys were on the show to promote their eagerly anticipated new single 'Live While We're Young' which is released this Sunday.
The boys also showed off their best dance moves during their appearance.
Alan Carr challenged the band to a dance off; however, unbeknownst to Alan the One Direction boys had a trick up their sleeves.
Rather than individually taking on the funny man, the fivesome attacked in numbers co-coordinating their best moves in sync.
Find out who won the dance off on tonight's Alan Carr: Chatty Man at 10pm on Channel 4.
