Good news for those who prefer their men non-threatening, sensitive and soul-patch-sporting and like their women bonier than the dumpster of a KFC: Orlando Bloom and Kate Bosworth may be back on the market.

"Entertainment Tonight" reports the fitful flames, who called off their nearly three-year romance in January 2005 only to reconcile a few months later, have gone belly-up yet again.

No word on what caused the supposed split, but it comes after a summer spent crisscrossing the globe promoting their respective big-budget flicks: Bloom, 29, was boosting the record-breaking "Pirates of the Caribbean: Dead Man's Chest," while Bosworth, 23, was out stumping for the more modestly grossing "Superman Returns."

The break-up also comes about a month after the humdrum honeys purportedly had a public spat during a stopover in Japan. According to the London Mirror, the argument was sparked after the cadaverous starlet allegedly tossed a cigarette butt and some litter on the ground at an environmentally friendly rock festival where Bloom was appearing.

"Orlando had a massive go at her," a snitch told the tabloid. "He said they were meant to be there to promote the environment and she was chucking litter around ... Kate kept saying, 'Nobody saw, I don't know what your problem is.'"

The pretty actor, who's been in California filming the third installment of the Johnny Depp-dependent swashbuckling franchise, was on his own at the Teen Choice Awards on Aug. 20, when he collected the coveted "Choice Hottie" prize, but according to E!'s Ted Casablanca, he may have already moved on with someone new. Details are sketchy, other than she's supposed to be "athletic" and he's supposed to be "entranced."

Right now, it remains unclear whether Bloom and Bosworth still intend to star together in the Depression-set adventure-drama "Seasons of Dust," which is scheduled to start shooting this fall.
