Brad Pitt Flashes Wedding Band?

New photos have surfaced of Brad Pitt wearing what seems to be a classic style wedding band. Cameras caught a glimpse of the sparkler on two recent occasions. The first was over the weekend when the A-list actor was out shopping with daughter Zahara for her birthday at The Grove in Hollywood, California. He was smiling and seemed to be in high spirits.  The second was yesterday on the set of his new film Moneyball.

Not too long ago, Brangelina gave actress Mindy Cohn, the godmother of two of their children, a huge 4-5 carat solitaire diamond ring as a thank you gift.  In an October 2006 interview with Esquire Magazine, Pitt said that he and Jolie would marry when everyone in America is legally able to marry (voicing their support for gay marriage).  So what are your thoughts on the ring?  Did they secretly tie the knot?  Is it merely symbolic?  Or simply just decorative?
