After a tearful goodbye to the crowds in London's Trafalgar Square, Emma Watson jetted into New York's JFK Airport as she took the Harry Potter finale to the US.

Iin the same outfit she departed London in, the young star still managed to look effortlessly fresh despite the eight-hour flight.

Relaxed and smiling, the 21-year-old actress was dressed in a pair of black skinny jeans a brown trench coat, a black trilby hat and her favourite Zadig et Voltaire 'Ailes Strass' ballerinas.

The young Brit has a busy few days in New York as she is due to appear on US TV screens in a one hour Harry Potter special programme hosted by Larry King which will be aired in America on CNN at 8pm on Sunday.
