It was a reunion of The Hills last night as Lauren Conrad met up with her former pals of the small screen Lauren Bosworth, Stephanie Pratt, and Frankie Delgado at LA's Voyeur. Lauren first swung by the same bash as mom-to-be Jessica Alba and her husband, Cash Warren, but soon met up with her MTV pals to get the evening started at the club despite hurting her foot recently. It seems LC, Lo, Stephanie, and Frankie have kept in good touch since their series ended last year, but Audrina Patridge, who has been working on her own new show, wasn't in attendance. Lauren was similarly occupied shooting a new program, but she's looking for new networks to work with after things fizzled with MTV. Today, though, Lauren and Lo's attentions were on more serious matters as they both tweeted their sympathies to those affected by the Japanese tsunami and urged followers to make donations to the Red Cross.
