Cameron Diaz and boyfriend Paul Sculfor apparently take their intimate relationship to the next level. The actress showed off a diamond ring on her wedding finger, fueling rumors that she is engaged to Paul.

The 35-year-old actress flashed the sparkling rock to photographers as she left the Nobu restaurant in Santa Monica on Wednesday, June 25. An eyewitness told The Sun, "She wasn't hiding the ring and quite proudly showed it off."

Cameron previously was spotted cozying up with Paul while shopping and dining together in West Hollywood on Sunday, June 22. The lovebirds were also snapped kissing and cuddling all over town throughout the entire day. An onlooker revealed to The Sun, "They kissed, held hands and walked with their arms around each other while shopping at the American Rag clothing store. They couldn't get enough of each other and didn't care who saw."

Cameron and Paul began to fuel dating rumors earlier this month and they recently enjoyed a stay at the swanky Chateau Marmont hotel. The actress, who was devastated by the death of her father earlier this year, split up from former beau Justin Timberlake in 2007. As for Paul, he previously dated Jennifer Aniston and they broke up in 2007.
