Orlando Bloom’s on-off girlfriend, Miranda Kerr, is reportedly insisting the actor clean up his act – literally.

It seems the Victoria's Secret model has had it with the actor's laid back attitude to personal hygiene.

A source tells PageSix.com: "Miranda thinks Orlando is too smelly. Recently, she asked him if he could wash his clothes and perhaps shower more often."

When he's in between films, the Pirates of the Caribbean star apparently "goes days without washing his clothes.

"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."

Adding to his general stink is Orlando's habit of sleeping with his dog, Sidi, and letting her slobber all over him.
