This time it looks like it's over for good. Reports say Orlando Bloom and Kate Bosworth have broken up.

Sources close to the couple claim they have decided to go their separate ways after four years of on-off dating.

The alleged break-up comes just months after rumors circulated that Orlando was planning to marry "Superman Returns" star Kate.

Just two months ago Orlando - who is currently shooting "Pirates of the Caribbean: At Worlds End" in California - was reportedly caught kissing and "dirty dancing" with "Romeo and Juliet" actress Claire Danes.

Guests at the lavish Raisa Gorbachev Foundation party in Northamptonshire, England, looked on in astonishment as the pair got close.

"He was kissing her neck and grinding against her. He didn't seem to care who saw it," said one guest.

Meanwhile, Orlando recently turned down a date with a fan. The British actor was having dinner with a friend at the Chateau Marmont hotel, in Hollywood, when the brunette admirer approached him.

"She asked him if he would like to accompany her to a party at an art gallery. Orlando declined politely explaining that his girlfriend, Kate Bosworth, wouldn't approve, but she wasn't taking no for an answer and tried again. He kept saying no and she eventually got the message and walked away," revealed a source.
