For women over the age of 18, looking younger is an absolute plus. Old enough to drive, marry, drink, join the army and see any film you want at the cinema, its all good. On the whole, looking younger at that age may let you get away with a child ticket on the bus, or at the movies, plus there's no need for make-up or expensive anti-ageing moisturiser, win-win-win. However when you're an international star and on an aeroplane alone, it truly is a little embarrassing to be asked where your guardian is. Sadly, that's precisely the situation that Harry Potter star Emma Watson found herself in recently.

She tweeted "Passport control:'unaccompanied minor?' Me:'sorry?' Passport control:'where is ur guardian?' Me:'I'm 22!!!!!!!'#neverwearingabackpackagain" followed by another, saying "The really sad thing is that this is not the first time this has happened". Sadly for her, backpacks are really 'in' right now - she may have to forego that fashion staple for a while. 

Since hitting the big-time with the enormous 8-film franchise of Harry Potter, the platform has provided Watson with other strands of her career including modelling for Burberry. She has also recently expressed an interest in writing: "I would like to adapt something." She told the Sun, "Maybe, eventually, even an original work. I would love to think I could write, but I would feel a bit intimidated. It's definitely something that I'd like to do though."
