Maria Shriver recently set off much hand-wringing when a ring appeared on her all-important finger, leading many to conclude that she'd made up her mind to take back hubby Arnold Schwarzenegger, despite his secrets and lies.

But we can all stop worrying, according to People mag, which says the sparkler in question belonged to her beloved mother, Eunice Kennedy Shriver, and she's been sporting it, apparently off and on, since her passing in 2009.

And a source denies rampant rumors that Maria has been experiencing doubts over pulling the plug on her 25-year marriage following a strong wooing campaign from Arnold, who has also been spied wearing his wedding band.

"The reports of a reconciliation are not true," the confidant tells the mag.

Instead, it seems the estranged pair's recent together-time, including spending Christmas with their four kids and taking in a Los Angeles Lakers game, is just good parenting.

Pronounces the insider, "Arnold and Maria will always come together when it comes to supporting and loving their children."

Shriver and Schwarzenegger split in May after he admitted to fathering a son with the family's longtime housekeeper. The prenup-free exes have reportedly been working to hammer out an agreement to divvy up their $400 million fortune.
