Those One Direction boys are such a bunch of little scamps!
The Little Things stars decided to treat some of their fans to a little prank for TV show Surprise Surprise.
They made their way to Madame Tussauds and found a little 1D-shaped spot and stood very, very still until the ladies turned up. They posed to have their photos taken with Harry Styles, Liam Payne, Louis Tomlinson, Zayn Malik and Niall Horan and when the moment was just right the boys jumped out at them.
The girls soon forgave them mind you...
