Orlando Bloom is too smelly for on-again, off-again girlfriend, Victoria's Secret model Miranda Kerr.

"Miranda thinks Orlando is too smelly. Recently, she asked him if he could wash his clothes and perhaps shower more often," sources tell Star

When he's not working on a film, the Pirates of the Caribbean star, 31, "goes days without washing his clothes," adds the source. "He'll wear the same jeans for a week before he throws them in the washer. Same goes for his sweaters, T-shirts and socks."

Since Miranda, 24, told him to clean up his act, Orlando has been trying. But, says the source, he's told friends "he doesn't know if this relationship will last."
