Lost beauty Evangeline Lilly knew she had hit the big time when a young fan stole her knickers off the washing line at her Hawaiian home.

The 26-year-old Canadian was amazed when a close friend recounted how she saw an adolescent snatching the underwear from her back garden.

She says, "I had a friend staying who heard a knock at the door while she was in the shower.

"By the time she got to the door, she saw a 12-year-old boy stealing my knickers off the washing line.

"I never got them back!"
