Former supermodel Christie Brinkley has fired her divorce attorney and reteamed with the lawyer who represented her when she split from Billy Joel. According to sources, Brinkley and Eleanor Alter had a series of heated disagreements leading to the split. Brinkley will now be represented by Bob Cohen when she returns to court on 16 July (07) to continue divorce proceedings from Peter Cook. Brinkley filed for divorce from Cook in September 2006, two months after reports surfaced about his alleged affair with an 18-year-old assistant.
