Attention, all Directioners.
Your favorite boy band just gave you the only gift you'll need this Christmas: Niall Horan dancing and singing in his undies.
While filming the behind-the-scenes special for NBC's One Direction: The TV Special, which aired Dec. 23 to a modest audience, the 21-year-old came bursting on to television screens almost in the buff, sending fans across several countries into fits and hysterics.
The toned Irishman frolicked about in the band's hotel laughing with his band and other mates singing their newest single, "Steal My Girl."
The Brit boy band is preparing to launch their Where We Are tour, promoting their fourth album, Four.
