Sweet's career began at age 19 when she had a chance meeting with Suze Randall. Ironically, she went to Randall's studio to accompany one of her friends, who aspired to be a model. When the photographer met them, however, Sweet was chosen instead. She began modeling for Randall, and soon afterwards was chosen for a centerfold spread in Penthouse magazine. She became Penthouse Pet for August 1998, which led to appearances in other men's magazines, including Perfect 10, Club, High Society, and Leg World.
