Rachel Bilson Looks So Young, She Was Mistaken For A Child At The Airport (VIDEO)

Rachel Bilson played a teenager on TV six years ago, but apparently she still totally looks the part.

In an interview with Women's Health U.K., the 31-year-old "Hart of Dixie" star talked about that time looking so young wasn't in her favor.

"I know I look super young," quotes E! from Women's Health. "I was flying back home into LAX the other day and the security guard at the airport stopped me and said, ‘Honey, where's your family?' And I'm like, 'I'm 31!'"

"Maybe when I'm 40 I'll appreciate it," continued the brunette beauty, "but as I get older and get wrinkles I'm worried it'll be, 'She's the weirdest-looking teenager I've ever seen.'"

We doubt that.

Funnily enough, 22-year-old Emma Watson had that exact same thing happen to her last month, when she was stopped at JFK airport and asked if she was an "unaccompanied minor." Seems to us like airport officials need to catch up on their YA shows and films.

In the interview, Bilson also talked about what goes into looking as fit and as fresh as she does and... Well, you're not going to like it. Her favorite food is Flamin’ Hot Cheetos, okay??

"I don't do the super-clean-living LA thing," quotes Daily Mail from her interview. "Everyone is obsessed with kale and hiking. And there's a massive amount of juicing going on."

She's also "not into the gym" but rather prefers "dancing or tennis."

Hey, some are just born this way, and that's what Hollywood is for. To learn more about Bilson's eating habits (she's obsessed with cereal. So cute!) and how she keeps the flame alive with beau Hayden Christensen, pick up a copy of Women's Health UK, on stands now (Feb. 6).
