One Direction

The teen craze unleashed by this 'X Factor'-winning London quintet arrives this month with a macro concert in Madrid's Vicente Calderón stadium. Niall Horan, Zayn Malik, Liam Payne, Louis Tomlinson and Harry Styles are the hottest boy band of the minute. So much so, that tweenie girls have been camping out at the gates where Atlético Madrid call home for two months to get as close as possible to their poster idols.

Despite their youth, the lads have already released three studio albums, 'Up All Night' (2011), 'Take Me Home' (2012) and 'Midnight Memories' (2013). Abraham Mateo, a Spanish singer also driving the girls mad, opens up for the band along with Australian cuties 5 Seconds of Summer.
