Friends are forever. Well, not if you're a reality TV star. Whitney Port and Lauren Conrad, two gal pals from "The Hills," are reportedly not the best of besties anymore, and it's all because of a tv show. "Whitney is upset because she thinks that 'The City' was canceled to make room for Lauren's new reality show," a source tells Us mag. "Whitney feels like she got the shaft." Oddly enough, Lauren's reality show didn't even get picked up by MTV; the network called it too "high brow." Still, it doesn't seem like they're on good terms regardless. "They're no longer friends," says Us's Senior Editor Ian Drew. "Whitney failed to show up for Lauren's recent birthday party in LA at The Roger Room last week. Another source says it was only a friendship for the show, don't buy it." *Sheds a single tear*.
