Recent photos of Maria with some supersized bling on her left ring finger, however, have sparked rumors that the 56-year-old mom of four was reconciling with the Terminator star.
But hold the phone on this one: The ring in question belonged to Maria's late mother, Eunice Shriver. Sources close to Maria Shriver confirmed to E! News back in January that her bling is actually an heirloom that she has been wearing since her mom's death in 2009.
And while Maria isn't wearing her wedding ring again, Arnold has been quite vocal lately about the collapse the couple's 25-year marriage while promoting his new autobiography, Total Recall: My Unbelievably True Life Story.
Arnold told Piers Morgan Maria was his true love and he "[takes] the full blame" for ruining their marriage. Being the classy lady she is, Maria has yet to speak out about Arnold's tell-all book tour.
And although she filed for divorce in July 2011, the duo has yet to finalize the process.
