Tilda Swinton isn't "remotely insulted" when she is mistaken for a man.
The Oscar winner, who claims airport staff often think she is male, says she doesn't care about other people's opinions because she is comfortable with herself.
The 54-year-old star said: "Oh, I think they're very tired, those people, they see somebody nearly six feet tall coming toward them with short hair, and they just say, 'Male assist.' So I'm not even remotely insulted.
"I have never been particularly hung up on what I look like. I was this height when I was 13, and you know, there's only so much I can do with myself."
The blonde beauty also isn't worried about getting older.
She explained: "Aging is not something to be feared. I'm interested in wrinkles appearing - I think it's kind of fascinating. I wouldn't want to be 23 again. And I wouldn't want to be 53 again! I live with the reality that my life just gets better."
And despite being the current face of Nars cosmetics, the actress admitted she rarely wears make-up.
She told the May issue of US InStyle magazine: "I don't [usually] wear make-up. I tend to look like a drag queen when I put all that stuff on.
"I will never be a bombshell. But I can dress up as one if I like."
