Maria Shriver -- I Got Something On My Ring Finger, Too -

Maria Shriver sure knows how to ring in the new year -- just days after Arnold Schwarzenegger wore his wedding ring out in public ... his divorce-shy, estranged wife was sporting something on her wedding ring finger, though it's not clear if it's the real deal.

The photo was snapped today in Beverly Hills -- interesting she wore something on that finger just after we posted the pic of Arnold.

TMZ broke the story ... Maria has been having second thoughts about divorcing Arnold -- despite the whole lovechild thing -- because of her deeply held religious beliefs.
