The world's most famous cheerleader told E! News on Wednesday that the Japanese powers that be had issued a warrant for her arrest for her role in a protest against the slaughter of dolphins and whales by local fishermen, one which necessitated Hayden's whole party leaving the country to avoid trespassing charges (not to mention all the relentless poking). Not that the plucky starlet's frightened, of course - despite the possibility of jail time, she made sure that E! knew she'd be out there again in a heartbeat: "I'd do it again. Very possibly, might do it again."
