The hotel heiress is being sued for breach of contract by bosses at Worldwide Entertainment Group Inc., who claim she neglected to honor promotion and publicity agreements for the film and owes investors a massive $8.3 million.
The movie executives claim Hilton was paid $1 million for her acting services and for "reasonable promotion and publicity" for the film, which featured the socialite/actress as the president of an exclusive sorority.
After the socialite's legal team failed to get the lawsuit dismissed in May, Hilton was forced to attend the trial to defend herself against the claims.
In true Hilton style, the hotel heiress attended court in a black dress and high stilettos, and even gave the judge a cheeky wave.
She told the courtroom that the film's failure had nothing to do with her -- insisting she takes promotional work for her ventures very seriously.
She told Judge Federico Moreno, "If I have my name attached to something, I want it to be as big as it can be."
Hilton went on to admit that by the time it was expected for her to promote the DVD release of the film, she was already booked up for rehearsals for her next film, The Hottie and the Nottie, in 2008.
The trial continues.
