According to US WeeklyNicole Richie and Jessica Simpson are caught in a bitter feud on the set of their upcoming NBC reality-competition series, Fashion Star.

Sources tell the mag the feud all boiled down to — what else? — fashion.

“[Nicole] thinks Jessica doesn’t have much of a high-fashion eye,” a source told US Weekly, adding that she “makes snarky comments about Jessica’s outfits.” Jessica, meanwhile, was said not to care about Nicole’s opinions, due in part to the success of her fashion line, which raked in a whopping $750 million in 2010.

Of course, as with many tabloid stories, the report turned out to be totally false. At least that’s what Richie alleged Thursday morning during an interview with Ryan Seacrest.

“[The story] couldn’t be further from the truth,” the 29-year-old starlet said. (Listen to the full interview here.) “I’ve known her for years …so I already knew who she was as a person. [She is] someone who’s very kind, very sweet and extremely smart. And a great businesswoman, and someone that I really respect.”

“I can understand that that’s probably exciting to read about,” she added. “But as far it being from the truth, it couldn’t be further … I actually couldn’t love someone or respect someone more.”

Well, so much for that.
