Cameron Diaz was all smiles at The Academy's Hollywood Costume luncheon in LA on Wednesday—perhaps she was preoccupied with thoughts of wedding planning? The actress and former BAZAAR cover girl took to the red carpet with some noticeable bling on her left hand, and guests at the event told People that she was "casually and constantly twirling her ponytail, showing off the ring and often playing with it," while seated at a table with Gwyneth Paltrow. The jewelry in question appears to be a double-banded gold-and-diamond ring, and though not traditional by any means, we wouldn't be surprised if Diaz's boyfriend, Benji Madden, selected the unconventional piece as an engagement token for the quirky actress.
