When Paris Hilton was a child she began modeling, most often at charity events. When she was 19, she joined with Donald Trump's modeling agency, T Management. Hilton has also worked with Ford Models in New York, Models 1 Agency in London, Nous Model Management in Los Angeles, and Premier Model Management in London. Her picture is in many advertisements, and some of them are Iceberg Vodka, GUESS, Tommy Hilfiger, Christian Dior, and Marciano. In 2001, people started looking at her as a socialite, and everyone called her "New York's leading 'It Girl'" (a girl who is good at knowing what clothes are stylish to wear and knows the latest gossip).
