Paris Hilton PHilton090708_01_X17.jpg Paris Hilton has joined the cast of director Todd Solondz's follow up to "Happiness," according to ScreenDaily.com.

Solondz is responsible for masterpieces such as "Welcome To The Dollhouse," and this new project is described as "part sequel, part variation" to his 1998 Golden Globe-nominated film, which included actors such as Camryn Manheim and Oscar-winner Philip Seymour Hoffman. Charlotte Rampling, Allison Janney and Paul Reubens (yes, that's Pee Wee Herman) will also be joining Paris in the untitled film.

Production is currently underway in San Juan, Puerto Rico, and a release date has not yet been set.
