Paris Hilton sported six-inch stiletto heels and a black dress and amused the judge with a little wave on the way to the witness stand.

Once on the stand, though, Hilton was businesslike when it came to defending herself against an eight million dollar lawsuit's claim that she didn't do her part to promote the 2006 box-office bomb Pledge This!

She acknowledged in court the movie didn't turn out very well but insisted she plugged it for everything she was worth.

"If I have my name attached to something, I want it to be as big as it can be," the 28-year-old heiress, model and actress testified.

"It could have been a lot better if it was done more professionally. I wanted it to do as well as possible."

Hilton is accused by an investor's lawsuit of turning her back on the film, a box office bomb that made just 2.9 million dollars, at a crucial time when it was being released on DVD and in foreign markets.

The lawsuit, seeking 8.3 million dollars in damages, claims she violated her contract by rejecting or ignoring requests by producers to appear on talk shows and do radio and magazine interviews for the film.

Hilton insisted she was never told her contract required appearances after the October 2006 premiere of Pledge This! and said she spent more than two years promoting it beforehand, including two high-profile trips to the Cannes Film Festival in France.
