Harry Styles, Liam Payne, Niall Horan, Louis Tomlinson and Zayn Malik love to party. So suffice it to say they were pretty excited to get to Las Vegas in June 2012. "The boys were hoping to go wild in Vegas by boozing and gambling into the early hours," an insider told U.K.'s The Sun. "But security at every casino in town knew who the lads were and threw them out because the legal drinking and gambling age in the U.S. is 21." But don't cry too hard for them. To keep the boys happy, management spent over $25,000 on a two-floor suite at the Palms, complete with hot tub, pool table and basketball half court.
