HARRY Potter” actress Emma Watson has grown up on screen before her fans’ eyes, but customs agents at Kennedy Airport apparently still see her as a kid.
The 22-year-old Brit revealed Monday in a series of Twitter posts that she was mistaken for an unaccompanied minor when she flew into JFK over the Christmas holidays.
“The really sad thing is that this is not the first time this has happened,” an embarrassed Watson tweeted.
She said she was asked where her parent or guardian was when she went through customs.
Passport control: ‘Unaccompanied minor?’ Me: ‘Sorry?’” Watson tweeted.
“Passport control: ‘Where is ur (your) guardian?’ Me: ‘I’m 22!!!!!!’
She said the episode taught her a lesson: “Never wearing a backpack again,” she tweeted.
Back in October, the youthful Watson gave a very grown-up interview to Glamour, dishing on hairstyles, fashion — and her dating life.
The onetime child star told the magazine she now works with a professional stylist.
“Yeah, I have to at this point,” she said. “When I was younger, I used to do it all myself, but I’ve had to get help because it’s gotten to a stage where I can’t show up in my Converses or whatever....
“You’re being photographed from every angle, so not only do you have to consider how the thing looks, but whether you’re going to be able to sit in it and whether people are going to be able to see up your skirt.”
Watson even ’fessed up about being caught kissing a male companion at the Coachella music festival.
“It was a huge crowd, and I thought there was no way anyone could get pictures of me, but somehow they found me.
“It’s difficult on my dating life, because anyone I get photographed with is automatically my boyfriend. So it just makes it look as if I’ve had, like, 6,000 boyfriends!”
The Glamour cover girl sported a short, chic hairdo, bare legs and a plunging black and gold necklace for her photo shoot with the magazine.
“Of course, men like long hair,” Watson said.
But the actress said chopping off her locks made her ooze confidence.
“I felt really good in my own skin,” she said.
