Kristin Cavallari Doesn't Think Minors Should Be Allowed to Do Reality TV

— -- When Kristin Cavallari was a junior in high school, she became famous for starring on the MTV reality TV show "Laguna Beach."

Now, she doesn't believe that teens should be permitted to do those types of shows.

"It was tough," she told OWN of making the show. "I still, to this day, think that you should have to be 18 to do a reality show, only because of my experience."

Cavallari, now 27 and the mother of two, said that when she was first cast, she didn't know what to expect. When the show aired and it was clear that she was being portrayed as the villain, she was devastated.

"I put up a wall and I put up a really tough exterior because I felt like they were really trying to take advantage of me," she said. "It was really hard."

Cavallari claimed that show producers told her then-boyfriend, Stephen Colletti, to also pursue another girl, Lauren Conrad, which caused confusion and hurt feelings. On top of everything, the show, "literally turned into an overnight huge success," which nobody necessarily expected.

"It was a really wild time in my life," she said.

MTV did not immediately respond to a request for comment.
