Paris Hilton is travelling to Ireland in a bid find out if she is a distant relative of British pop star Lily Allen. The hotel heiress will attend the Flatlake Literary Festival in County Monaghan later this month (25-26Aug07) - an event organised by Allen's uncle Kevin - to search her family tree. Keith Allen says, "We believe Paris wants to come to the festival which is at my in-laws' place at Hilton Park, to check out her Irish ancestry. "They may be related."
