Hilary Duff left the french radio "NRJ" and went to her hotel in Paris today wearing jeans and a green blouse.

She was busy promoting her upcoming book "Elixir," a young-adult romance with a paranormal element, which will be released on May 3.

Hilary most recently starred in "Beauty & The Briefcase" about determined fashion journalist Lane Daniels (Duff), who weighs love against ambition while researching the Cosmopolitan cover story that could make or break her career.
