    Conrad said her reality TV days are over, but she doesn't regret letting so much of her life play out on camera.
    "The show isn't something I like to re-live," she said. "Looking, back I would absolutely do it again. It brought so much good to my life. While it was hard at times, it brought me to a place where I'm really happy and I get to do what I love," Conrad said.
