Birds of a feather stick together! Hopefully Paris Hilton has paved the way for bff Nicole Richie in the clink. Us Weekly has confirmed that Nicole will serve out her four-day sentence at the Century Regional Detention Facility at Los Angeles County's women's jail in Lynwood -- where Paris served her very taxing 23 days. "Nicole Richie's attorney has indicated that she wants to do her time in county jail," L.A. County Sheriff's Department spokesman Steve Whitmore tells the mag. "Lynwood is the only county jail for women in Los Angeles, so if she does go to county jail she will go to Lynwood." When asked whether the expecting star could possibly get a reduced sentence for good behavior, Whitmore refused to speculate, saying, "All things are decided upon entering the jail." No doubt Paris will take the time out to visit her good friends at the facility -- and see Nicole while she's there, too, of course.
