The most unlikely Hollywood feud in memory has broken out between Paris Hilton and - get this! - British comic Ricky Gervais.

Gervais - creator of TV-comedy phenomenon "The Office" and, more recently, the HBO series, "Extras" - apparently snubbed the blond heiress.

Hilton had asked to appear in an episode of "Extras" next season - and Gervais said no thanks.

Hilton has decided that he's too insecure to work with someone of her, um, stature.

"I guess he's obviously scared of starring alongside an A-lister," Hitlon told the San Francisco Chronicle over the weekend.

A number of Hollywood stars portrayed themselves in the first season - including Ben Stiller, Samuel L. Jackson and a cursing Kate Winslet.

No reply yet from Gervais.
