But if she were looking, she tells British Elle in its August issue, "I'd like someone who makes me laugh. I like an intellectual guy, because I love to read. If they like movies, books and music, we're pretty alright.
"And I'd like someone who's mature; God, I can't take another immature person!'
Barton, 21, won't name names, but she's had her share of high-profile relationships. She and rocker Cisco Adler split in February, shortly after a nude photo of him surfaced among Paris Hilton's belongings.
Before that, the O.C. actress dated oil heir Brandon Davis. They broke up in 2005 after more than a year together; Davis was later caught on tape making vulgar remarks about Lindsay Lohan.
Although Barton knows both Hilton and Lohan, she says she's not a part of their crowd. "The media has created a fake 'Young Hollywood' where everyone hangs out together and everybody knows each other," she tells Elle. "It couldn't be further from the truth. I feel so, so different from those girls."
She admits that she got caught up with the wrong scene when she first arrived in Hollywood as a teen: "When I got there I didn't know anything about the business, and you don't make the best of friends. You make a few mistakes when you're that age and it took me a while to find the friends I needed, to be truly comfortable."
And although she works out when she travels, she insists she never diets. "I had waffles this morning!" she says. "We've always been thin in our family – I'm lucky." For exercise, she walks her dogs every morning. "There are some things I like about L.A. You can have a really healthy lifestyle, and I love running with the dogs on the beach. It's just the social scene is horrific!"
