Actress sparks engagement rumours with diamond ring!

There may be wedding bells in the air for Cameron Diaz and her boyfriend Benji Madden!

Cameron was spotted with quite the diamond on her left-hand ring finger when she attended an event in Hollywood and then later out on a dinner-date with her man.

The couple have been together since April, after being introduced by Benji’s sister-in-law, Nicole Richie.

The former reality TV star turned designer is married to Benji's brother and Good Charlotte frontman, Joel Madden, the couple have two children together, Harlow and Sparrow. 

Nicole joked recently that the relationship was entirely her doing, saying: “I’m going to take responsibility for everything. I approve of anything that’s going to make Benji happy.”

Aww – how sweet, we wonder if Nicole will design Cameron’s wedding dress…or are we jumping ahead of ourselves?!
