Tori Spelling Rings in The New Year

Tori Spelling spent the last day of 2013 re-setting her wedding ring ... back on her finger.

Tori has been out sans ring ... since reports surfaced that hubby Dean McDermott cheated on her with a woman in Canada ... but she clearly decided to send a different message during a New Year's Eve burger run.

Tori has said nothing about the allegations. Tori posted video XMAS morning of her and the kids opening presents ... but Dean was nowhere in sight.

12:25 PM PT -- A short time ago, Tori tweeted a photo of her family -- including Dean -- wishing fans a happy New Year.
