Emma Watson was stopped at US immigration because officials thought she was a child.
The 22-year-old actress was stopped at JFK airport in New York where she was questioned by officials at passport control who believed the youthful looking Harry Potter star was an unaccompanied minor.
She tweeted: "Passport control: 'unaccompanied minor?' Me: 'sorry?' Passport control: 'where is ur guardian?' Me: 'I'm 22!!!!!! #neverwearingbackpackagain
"The really sad thing is that this is not the first time this has happened (sic)."
A source told The People newspaper: "Emma was mortified. Not only did they not know who she was they thought she was a child. It was very embarrassing but she managed to awkwardly laugh it off.
