Cameron Diaz has sparked engagement rumors by sporting a huge ring on her wedding finger.

The “Charlie’s Angels” actress appeared to flash the dazzling ring at photographers as she left the Nobu restaurant in Santa Monica yesterday, indicating that her relationship with new beau Paul Sculfor may have taken a more serious turn.

Earlier this week the 35-year-old star was pictured looking blissfully happy as she kissed and cuddled the bricklayer-turned-model, who previously dated Jennifer Aniston, during a day out in West Hollywood.

The celebrity couple couldn’t keep their hands off each other as they enjoyed a dinner date before strolling to a nearby boutique.

Cameron Diaz, who was devastated by the death of her father earlier this year, has been single since splitting from Justin Timberlake in 2007.

Paul Sculfor, 35, briefly dated former Friends star Jennifer Aniston earlier this year.

He is also a close friend of Victoria Beckham and has dated TV presenter Lisa Snowdon.

A matter of mere days ago the internet was abuzz with rumors that Cameron Diaz was dating Jennifer Aniston’s ex, model Paul Sculfor. The pair were seen taking a walk and making out on a beach in Los Angeles on Monday – a classic romantic combination. Later that day, Diaz was photographed driving (with a different man in her car) with a massive ring on her left hand, leading us to wonder if she’s planning on tying the knot.

You don’t exactly go to Nobu when you want to keep things low key and private. That sure looks like an engagement ring to me. If so, congrats to Cameron and Paul! If not… excellent publicity ploy.

Jennifer Aniston has decided to refuse to sleep with any of her boyfriends until she finds “true love.” A source claims that the actress, who was once married to Brad Pitt, is “saving herself.” A source close to the actress said:

“Jen’s made it clear to men who want to date her she’s not interested in one-night stands or flings. She’s looking for true love and she’s saving herself. Jennifer told me: I’m looking for the person who will love me for who I am, not what I am. I am not interested in sex for the sake of it.”

Jennifer is said to be dating actor Aaron Eckhart, her “Traveling” co-star. Following her divorce from Brad Pitt, she’s still looking good and has dated Vince Vaughn, Paul Sculfor, and was linked to actor Jason Lewis as well.
