Cameron Diaz and Paul Sculfor are Splitsville

Cameron Diaz is saying adios to her boyfriend of almost a year, British model Paul Sculfor.

The two have apparently been having a hard time squeezing in enough time together, what with her busy filming My Sister's Keeper and him jet-setting around the world for a variety of modeling gigs. The twosome had grown quite close and had even begun co-habitating, but Cameron has reportedly asked for the key back to her L.A. home.

A source for Britain's Grazia magazine says, "They have fallen out of love. They didn't seem to find time for each other anymore. Paul is not too enamored by Los Angeles and wants to be where his friends are. Cameron thought she could settle in England but missed her old life too much. The romance just died."

Of course, Cam is taking the break up like a champ. She was recently spotted partying the night away at Chateu Marmont and flirting with a bunch of guys. When a friend asked her about Paul, she rolled her eyes and dismissed the question with a wave of her hand. Looks like this blond bombshell is looking forward to being single again!
