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 Angelsâ 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 rumors 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.
