Fire destroyed the rented home of "Lost" star Evangeline Lilly in coastal Kailua on Oahu island Wednesday, officials said. Lilly was not at home, and no one was injured.

Two roommates were also not home when the fire broke out sometime after 6:30 a.m., authorities said. Investigators were searching for a cause.

"Unfortunately, it is true that the home she rented in Hawaii did burn down this morning," Lilly's publicist Cara Tripicchio said in an e-mail. "Evangeline was on set already when the fire occurred and luckily, her roommates were not in the house either.

The home was "fully involved" in flames when firefighters arrived, said Capt. Kenison Tejada, spokesman for the Honolulu Fire Department.

"We stopped the fire from spreading," he said. "It took us maybe 15 to 20 minutes to knock down the main body of fire."

Only the roof and a couple of interior walls were left standing, and most of the home's contents were destroyed, he said.

Lilly plays Kate on the hit ABC drama, which films in Hawaii.
