Paris Hilton promotes herself like none other. She just didn't honor a deal to promote herself as part of the film Pledge This!, according to its producers.

A Miami judge today that he will not throw out a breach-of-contract lawsuit brought against the ho-tel heiress by the distributors of the 2006 drivel.

Investors claim Paris' failure to abide by her contractual obligation to adequately plug the straight-to-DVD sorority flick resulted in a loss of $8.3 million.

Ironically, she's now indirectly doing more to promote it - testifying how she Googles herself to remember what she said or did, rather than keep records, and so on - than marketing managers could have possibly dreamed of.

Her attorney claimed her to be "the single busiest person on the planet," but a judge didn't throw out the case, telling her she must stand trial June 8.

A judge's ruling brought Paris Hilton to her knees. Figuratively.

As for her other projects less likely to result in lawsuits, she's soaking up the sun in Europe, with beau Doug Reinhardt, promoting the upcoming documentary Paris, Not France, appearing this week at the Cannes Film Festival.

She's also already hyping the forthcoming Season 2 of My New BFF on MTV, something that seems to hearken back to her Pledge This! days.

"It was basically Paris' sorority house," she tells E! News "It's about sisterhood - there's pledging, there's crazy challenges. We had the best time. We started out in Las Vegas, and these kids really were up for anything."

Awesome. The second season kicks off June 2.
