Hollywood actress Cameron Diaz has sparked rumors she is engaged to British model Paul Sculfor - after she was photographed wearing a diamond band on her wedding finger.

The Charlie's Angels star has reportedly been dating Sculfor - who was recently linked to Jennifer Aniston - for the last few weeks but neither have officially confirmed the relationship.

However, the pair stepped up speculation they are romantically involved after they were spotted locked in a passionate embrace following a romantic meal in Santa Monica, California on Monday night.

And now Diaz has been snapped sporting a large diamond ring on her left hand, prompting rumours that her relationship with the former brick-layer could be more serious than previously thought.

The 35-year old actress split from pop star Justin Timberlake last year, she was subsequently linked to Jennifer Aniston's current love interest - rocker John Mayer.
