One Direction's perfume Our Moment has become the fastest selling perfume of the year.

The "Little Things" boy band - consisting of Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson - are once again smelling sweet success as their first ever fragrance, marketed towards their ever-loyal female fan base, has sold more than any other scents in 2013 in the UK. Our Moment is also retail chain The Perfume Shop's best selling fragrance in history and the company was even forced to bring in extra staff to meet demand from the group's obsessed admirers.

"The success of Our Moment is something One Direction are very proud of. The incredible level of sales we've seen so far of Our Moment and the overwhelming feedback given by fans is a reflection of the band's involvement in every stage of its creation and their desire to make a personal and unique product for their fans," said Faye Langworthy of One Direction's management firm, Modest! Management.

The heartthrob band are no strangers to sending their fans into a tizzy, with more than 20,000 devotees congregating in London's Leicester Square in anticipation of the world premiere of their 3D documentary One Direction: This Is Us in August.

Meanwhile, the "Best Song Ever" hitmakers are set to give back to their fans with an entire day dedicated to their global supporters. The group will present a seven-hour global live stream, interacting with fans around the world, on November 23. "1D Day is all about giving back to our amazing fans for supporting us for the past three years. When we suggested it we never thought anyone would let us loose live all day - we cannot wait!" Liam said.
