Paris Hilton is not renowned for her acting skill, however, she was cast in the 2005 film 'House of Wax', in which she is killed. The reason for her getting the role is probably because she is a 'sexual icon' and many adolescent boys and young men, would probably be more likely to want to watch the film, given it has a topless shot of Paris Hilton.

So it was important that we cast someone who would be considered an attractive girl by the audience.
Chloe Roberts was a suitable actress for the role as she is blonde and attractive, and was perfect for the role.
