The Post is reporting that Caroline Giuliani, the former mayor's youngest child, was arrested today at the Sephora on 86th and Lexington-near the home of her mother Donna Hanover, Rudy's ex-wife- for allegedly shoplifting from the cosmetics store. The 20-year-old was caught in the act at 3:30 p.m., the Daily News alleges. This is the conversation I had with a Sephora employee shortly thereafter.
