"I am single and they want me to date on the show, which I'm kind of excited about," the 22-year-old goes on. "They'll introduce me to guys, and if goes somewhere, they'll follow it. If not, it'll be over."
Cavallari says she didn't push her former foe, Lauren Conrad, out of the show.
"I had nothing to do with that! She was leaving, and I thought it was a good time to come in because she's gone," Cavallari says, adding that she'll "hopefully" become the next narrator.
