Nicole Richie Wears Wedding Band?

Nicole Richie is a jewelry maven, with her House of Harlow 1960 jewelry line hitting the big time and her signature boho chic style influencing fashionistas from coast to coast. But the former reality star is making news for jewelry of a different sort this week.

Richie has been spotted by X17 wearing what appears to be a gold wedding band on, well, the finger that tells the world that you're hitched. Despite denials from hubby, Joel Madden, to the contrary, Nicole seems to enjoy flaunting the ring finger bling and keeping us all guessing in the meantime.

What do you guys think? Did she and Joel run off shotgun style before their latest addition (a son named Sparrow) arrived? Or is she just having fun with the paps on this one?
