For all of our loyal directioners: Here's your chance to own Niall's underear! 

According to Perez Hilton

"One Direction's frosty-locked cutie Niall Horan has signed a pair of his Calvin Klein tighty whities for UK's Now! Magazine…

And the mag is offering them up as a PRIZE for a voucher-collecting contest!"

To enter, fans must collect the vouchers from the next five issues of Now Magazine and send them to the magazine’s office.

GOOOOD LUCK!
