Paris Hilton arrived at the Ferguson U.S. Courthouse in downtown Miami at 8 a.m. Friday to testify in a lawsuit accusing her of not doing enough to promote her 2006 flick National Lampoon’s Pledge This!

She is scheduled to take the stand in her own defense Friday.

Hilton, who arrived with her attorneys and body guards, was wearing a sleeveless, slightly pleated black dress with a bow at the waist and black platform pumps. Her hair was in a bun, and she used a simple black head band.

In the movie, the 28-year-old heiress starred as a hottie sorority president at the fictional South Beach University.

On Thursday, Hilton showed up for her first day in court a little jet lagged after arriving in Miami on a flight from Dubai at 11:30 p.m. Wednesday.

She eschewed her traditional micro-skirt for a staid (for her) sleeveless, black-and-white tea-length number and black pumps, along with a Chanel handbag, sedate jewelry and a not-so-sedate flapper tiara in her hair.

Her blond extensions were put up into two long ponytails, which she fiddled with the entire time she was in the courtroom.

The lawsuit brought by movie investors seeks more than $8 million. They claim Hilton reneged on a contract to promote the film, including its DVD release. They say she refused interviews and other promotional opportunities.

Defense attorney Michael Weinstein countered Thursday that between December 2006 and May 2007, Hilton ”promoted the hell out of this movie,” in which she had her first starring role (unless you’re counting her infamous One Night In Paris), and for which she received a cool $1 mil salary.

She stopped promoting the film in June 2007, when she entered a California jail after a DUI conviction. Hilton ”fulfilled the norm of what most Hollywood actresses do,” and attended the film’s premiere, Weinstein said.

Chief Judge Federico A. Moreno cracked jokes during the arguments. ”How long does she have to promote this thing? Like, would Ronald Reagan promote a movie from the 1940s? It would be ridiculous,” Moreno said.

Moreno seemed to be leaning toward a settlement, telling the attorneys where the lounges were so they could “iron things out.”

Moreno also had another suggestion: “While Paris is here, why not promote it now? All weekend will be a lot more than 35 minutes in Tokyo.”

Hilton contends she plugged the movie extensively and met the contract’s requirements. She said the producers made unreasonable demands for appearances when her schedule was full.

The movie cost $7.5 million to make but earned only about $2.9 million.

Hilton will be in town through Tuesday to defend herself. No word on where she’s staying.
