Bring on the bling, Cam! As Us Weekly exclusively reported on Friday, Dec. 19, Cameron Diaz is engaged to marry Good Charlotte rocker Benji Madden after seven months of dating. So now the question is: Where's the ring?

The Other Woman actress, 42, has recently been spotted wearing a suspiciously sparkly bauble on her left hand. On Wednesday, Dec. 17, she flashed the ring while walking through New York City's JFK airport with her newly minted fiance.

The gold band, which appears to have at least one glittering stone embedded in it, was also visible when she taped her appearance on The Graham Norton Show in London on Tuesday, Dec. 16. She wore it along with another skinnier gold ring on the same finger.

"Everyone thinks it's wild but is so happy for them," a source told Us of the Charlie's Angels star and Madden, 35. "Benji 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." 

This will be the first marriage for both. Prior to meeting Madden through pal Nicole Richie (whose husband is Benji's brother and Good Charlotte bandmate Joel Madden), Diaz famously dated Justin Timberlake and Alex Rodriguez, among others.
