It's been quite a year for the cast of The Hills! In case you've been living under a rock lately, Speidi got hitched, Audrina accused Lauren of hooking up with Justin Bobby, and Whitney landed a new gig at DVF in NYC that we'll be able to watch closely on her spin-off, The City. One of our fave staples on The Hills is Lo Bosworth, who shook things up by adding drama to the house with Audrina and Lauren and never backed down from an argument. She's always been there to give her opinion and sometimes her fair share of dirty looks. Check our chat with Lo, and get ready for the season four finale of The Hills!
