Lauren Conrad was cheated on while filming “The Hills.” LC was known among the cast of (forgive us) bobbleheads as the wise, driven, ambitious voice of reason amongst the babble of Heidi, Audrina and the rest. No matter — Conrad says her boyfriends were still unfaithful.

more LC after the hop…

LC doesn’t mention which were but says:

“I knew back back then [that] I was being cheated on,” she admits in the March issue of Seventeen magazine (via usmagazine.com). “I overlooked it.” Not any more. “The more confident me has come to the point where I’ve finally realized it’s not something that everyone does. It’s not okay to have your guy hook up with someone else. You deserve more.”

Lauren also tells the magazine that many of her best friends weren’t featured on the MTV show.

“Most of my closest friends were never on the show; my family was rarely on…It’s not normal to put every part of your personal life on camera. You have to have something for yourself or you’ll go crazy.”
