A 53-year-old was arrested at the Kennedy family’s Hyannisport home last night after telling police he was in search of the “Dark Horse” singer. James Lacroix, who was chilling in the kitchen when police arrived, first aroused suspicion when he answered the house phone. Ted Kennedy Jr. was calling to check on his 16-year-old son and the voice of a stranger on the other line was enough for him to call the cops. Katy Perry, meanwhile, was in Montreal dressed like a palm tree.
