High school is long over, but the friendship between Laguna Beach's Talan Torriero and Kristin Cavallari may never end. "Kristen and I, over the last, I would say, five years, have developed such a great relationship. I consider her one of my closest friends," Talan, 39, exclusively shared with Us Weekly ahead of The Roku Channel's The Reunion: Laguna Beach. "I call her for business advice. I call her for personal advice." And sometimes they even talk about dating.
