But there's just something about Kristin's Laguna rival, Lauren Conrad, that's more down to earth. Wholesome. Innocent. She's America's sweetheart, the girl from the multi-million dollar oceanfront mansion next door.
The star of MTV's The Hills explains in the new issue of Cosmo Girl that she's always been more reserved and conservative than her peers.
"Sometimes I look at what really young girls wear and I can't believe it - I have underwear that covers more than what some of them have on!"
Unlike the many Paris Hilton clones begging for publicity by flaunting their sexuality, Lauren wants her fans to know that classy is sexy, too.
"I think it's important that girls know that they can be attractive and sexy in a classy way and that guys actually like that more than when they see girls who show a lot of skin," LC said.
"For me," Lauren says. "I like clothes and I like to wear them to cover up."
You go, Lauren. You go.
