LOS ANGELES -- As Paris Hilton adds Lindsay Lohan to the growing list of her former gal pals, wealthy friend Brandon Davis weighs in on the "Just My Luck" star's lack of sex appeal.

In a three and a half minute video on TMZ.com, Davis is seen club hopping on Tuesday night (May 16) and goes on a tirade about Lohan's anatomy, using a word that won't be found in Webster's: "firecrotch."

He talks at length about her genitalia, fixating on her freckles and red hair down there, but denies ever having seen her naked because he doesn't find her attractive. He also refers to Lohan's ex-boyfriend, "That '70s Show" star Wilmer Valderrama, saying, "Who would want to f*** her? Who? Wilmer? Is Wilmer like in a mariachi band?" and then brings in Lohan's dad, who he deems "hotter than [Lindsay]."

Davis heaps on the insults, finally commenting on her financial worth.

"I think she's worth about $7 million, which means she's really poor," says the billionaire's grandson. "It's disgusting. She lives in a motel in New York."

All the while, Paris is seen walking next to Brandon, laughing at his comments and holding a cell phone up to her ear. At one point she looks like she's whispering something (possibly encouraging) to Brandon.

In a statement to TMZ, Hilton's publicist states: "The only thing I want to underscore is the person making the statements was not Paris Hilton. It is unfair to characterize Brandon's statements as being reflective of Paris' feelings about Lindsay. We're dealing with two different people. It was Brandon who was speaking, of course there are moments when Paris was laughing, but she never said anything. Brandon was speaking for himself not for her. Personally, I found the incident unnecessary."

Mintz also comments on Hilton cell phone use during the incident.

"Paris uses her cell phone as a defensive tool. Many times when you see her photographed in a crowd situation, she puts it up to her ear so she doesn't have to speak," says Mintz. "In the cacophony and din of screaming, nobody could have had a telephone conversation. Reporters were asking her questions about Lindsay that she did not want to answer, so she put her cell phone up to her ear. Brandon was not speaking for Paris. Period."

Davis is the grandson of late oil billionaire and film mogul Marvin Davis. Davis, the foul-mouthed younger one, once dated Drew Barrymore after she split with husband Tom Green and most recently went out with "The O.C.'s" Mischa Barton. The two were introduced at a charity event in February 2004, dated for about a year, and then broke up in July 2005.

Hilton has a history of "breaking up" with her party girl friends. She and her ex-BFF Nicole Richie still aren't talking despite co-starring in the upcoming of "The Simple Life" together. Hilton also fell out with Mary-Kate Olsen when she stole the twin's boyfriend, Greek shipping heir Stavros Niarchos. They recently broke up amidst rumors that Lohan was seen canoodling with him.
