Orlando Bloom turned down a date with a fan - so not to upset his girlfriend Kate Bosworth.

The 'Pirates of the Caribbean: Dead Man's Chest' star was having dinner with a friend at the Chateau Marmont hotel, in Hollywood, when the brunette admirer approached him.

According to America's People magazine, an onlooker revealed: "After talking to him for a while 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."

Bloom recently revealed how he would never cheat on Bosworth - because he is too tired to love someone else.

He confessed: "I don't have a problem with groupies. But when you are onsetor have been promoting all day, the last thing you want is a load of ladies knocking on your door."
