The hotel heiress and The Simple Life star, 24, tells Newsweek magazine that when she was younger, "I thought it was cute to play a dumb blonde. On TV, I do it because it's funny. I consider myself a businesswoman and a brand."
All that is expected to change now that she is engaged to Greek shipping heir Paris Latsis – with Hilton saying she expects to become a mom.
"I don't enjoy going out anymore," she says. "It's such a pain. It's everyone saying, 'Let's do a deal! Can I have a picture?' I'm just, like, 'These people are such losers. I can't believe I used to love doing this.'"
