Harry Styles has his eye on a new woman.

The One Direction heartthrob was spotted leaving The Box nightclub in Soho, London, with TV presenter Billie JD Porter - who presents Channel 4 show 'The Joys of Teen Sex' - on Sunday night (17.02.13) after playing a DJ set.

Harry and Billie have known each other for a short time and the pair are said to have ''clicked'' during their evening together.

A source told The Sun newspaper: ''Harry's always liked Billie - he's had his eye on her for a while. They've flirted with each other before but on Sunday night things really clicked.''

The 19-year-old heartthrob, who split up from Taylor Swift in early January after a brief but intense romance, had been spinning tracks alongside DJ Chelsea Leyland for jeweller Dominic Jones' London Fashion Week after-party.

Meanwhile, Harry and the rest of the group - Niall Horan, Louis Tomlinson, Liam Payne and Zayn Malik - have each interviewed and hired their own female personal assistants to help organise their busy schedules along with receiving the help of; managers, publicists, financial advisers, stylists, around-the-clock security and drivers and asset managers.

A source told the Daily Mirror newspaper: ''The guys have incredibly manic professional and personal lives, and they started getting stressed out about their ever-increasing workload.

''Obviously the record label don't want them burning out, so they came up with the idea of letting them appoint personal assistants.

''The idea is for the PAs to run their diaries on a day-to-day basis, and make sure they turn up to dentist appointments and photo shoots. With the world tour coming up, it is essential they are on top of everything and put under as little stress as possible.''
