While many Eastern European stars tend to work predominantly for the European studios and websites, Diana Doll has focused more on the American market. Her first genuine appearance in an American hardcore release was in the 2003. During 2003, she had releases from both European and American studios and in the following years has appeared to divide her time between the two continents. Diana Doll was previously known as Sue Diamond, but changed her name due to being confused with fellow Slovak porn actress Suzie Diamond.
