Lauren Conrad is the center of this tree because everyone is connected to her. Sure she's not on the show anymore, but all these people have dated, worked with, been friends with, lived with, etc. She is the show's matriarch.
Lauren went to high school with and starred on "Laguna Beach" with Kristin Cavallari and Lo Bosworth, she also dated/starred on "Laguna Beach" with Jason Wahler, who made an appearance on "The Hills." Kristin, who joined the "Hills" in its fifth season, had previously dated Brody Jenner, who also dated Lauren. Brody most recently had eyes for former playmate Jayde Nicole.
Kristin also dated Justin Bobby who dated Audrina Patridge, which brings us to Heidi Montag because both ladies have lived with Lauren at one point or another. We all know you can't utter the word "Heidi" without then mentioning her hubby Spencer Pratt. He's related to Stephanie Pratt (his real sister) and Holly (his sister-in-law). And, he's had some issues with neighbor Enzo and Stacie the Bartender (who Kristin kissed last season in Vegas!).
Finally we're left with sweet-as-pie Whitney Port, who fits in because she worked with Lauren at Teen Vogue. She's now living and working in "The City" with Kelly Cutrone, who once also employed Lauren.
