Evangeline Lilly

An Internet rumor claiming that Evangeline Lilly is auditioning for fall 2009 pilots — and thus may soon be leaving the role of Lost's Kate — has been summarily dismissed as false.

"None of this is true, not even remotely," a source close to the actress tells TVGuide.com.

So, from where was this far-out fable born? While the original online account cites a "solid" source as saying that Lilly is putting out feelers, the writer of said story "never called anyone to clarify [her claims] — not ABC, not Lilly's publicist, not her agents," says our own insider. "It was quite irresponsible."

Both ABC and Lilly's spokesperson declined to comment for this story.
