Cameron Diaz definitely isn't trying to be sly about this! In fact, it seems like she wants to show off her new bauble...

On Monday afternoon the 42-year-old actress grabbed coffee in West Hollywood, and she gave us a peek at a sparkly rock on her left ring finger. This appears to be the same one she was spotted wearing a few days ago in New York City, and it has a number of tiny diamonds embedded in the thick gold band.

Cameron and Benji haven't released a statement about the matter, but after getting a peek at this, that's all the confirmation we need!

"Everyone thinks it's wild but are so happy for them. Benji always tends to fall in love easily, but this time it's for real and he landed a great girl. They obviously both make each other incredibly happy and there's nothing better than that," a source told Us Weekly, who first broke the news.

Nicole Richie introduced the pair, who first stepped out as a couple last May.
