MTV’s “The Hills” babe Audrina Patridge was spotted showing off some skin in a red mini-dress on her way to a studio in La. The reality TV show star was beaming even if there have been reports saying that her friend Lauren Conrad is in trouble with the authorities due to the fact that Audrina’s current residence is a guest house located at the back of Lauren’s home. The City of Los Angeles’ Department of Building and Safety is saying that the back guesthouse is illegal since only one dwelling, Lauren’s main house, is permitted. No word yet from the two celebs and MTV, but maybe it’s not that big a deal since Audrina looks unfazed in this photo.
