Emma Watson Stopped: 22 year-old actress mistaken for a child at passport control

Having growing up in the spotlight as a child star of Harry Potter, Emma Watson often had to fight to convince people she's all grown up.

While many of us adult women would love to look younger than our years, the English star's youthful looks backfired when she was mistaken for a child.

The 22-year-old was travelling solo over Christmas when she was stopped at passport control by an official requesting a parent of guardian.

Taking to Twitter after the embarrassing incident, Emma wrote: 'Passport control: 'Unaccompanied minor?' Me: 'Sorry?'

Passport control: 'Where is ur guardian?' Me: 'I'm 22!!!!!!!' #neverwearingabackpackagain.

'The really sad thing is that this is not the first time this has happened.'

Fortunately, Emma would have proof of her age on her as she was requested to show her passport with her date of birth.

Embarrassing: Emma shared her misfortune with her Twitter followers

Meanwhile, Emma admitted she was hoping to keep her New Year's resolution to speak French fluently.

Emma was bo in Paris to her British lawyer parents and spent the first five years of her life in France.

She told Marie Claire magazine: 'I always have the same New Year's resolution: to speak French fluently.

'I get a huge wave of nostalgia when I come into the Gare du Nord. There's such an emphasis on culture, art and music. And I'll do anything for a warm baguette.'
