Emma Watson, star of the hugely successful Harry Potter franchise, jetted out of London this morning after an emotional night having attended the world premiere of the final film in the Harry Potter franchise, 'Harry Potter and the Deathly Hallows Part II'.

Addressing the large crowds who gathered outside Trafalgar Square to see her and fellow co-stars Daniel Radcliffe and Rupert Grint make their way down the red carpet, Herald Sun report Watson broke down in tears exclaiming "It's overwhelming to try to find the words to say what I want to say, but I have been so privileged to play this role and be a part of these films" she added "I've had the most amazing 10 years of my life. Thank you so much." Describing coming to the end of the franchise as "bittersweet", Watson is however relishing a return to normality, saying "It's the little things that keep you sane."

Emma Watson, having spent the past few days in London conducting interviews and attending the premiere itself, flew out of Heathrow this morning for America, where she is due to appear in an one hour Harry Potter special programme, hosted by Larry King and airing in America on CNN at 8pm on Sunday (10JULY11).
