malibu sunglasses Maria Shriver katherine schwarzenegger christina maria aurelia schwarzenegger phones shawl skirt Ow ow!

Maria Shriver stepped out to run in errands in Malibu with daughters Katherine and Christina over the weekend, and the 56-year-old has never looked better, donning a tight white skirt that shows off her incredible body. Something else that caught our attention? The mysterious ring on her wedding finger!

Her ex Arnold Schwarzenegger has been on a media tour promoting his new memoir Total Recall, and in the process he's made a fool out of his former wife by admitting to affairs with housekeeper and baby mama Mildred Baena, as well as Rocky actress Brigitte Nielsen among others.

The Terminator star is still holding out for forgiveness, though!

The former California governor recently told Piers Morgan that he acknowledges his mistakes and hopes to make amends with his spouse of 25 years. " [I] hope that Maria and I can come back together as husband and wife and as a family with our children," he confessed to the talk show host.

It's my fault. There's no one else to blame. I screwed up badly and I take the full blame for it. I mean the thing that I cherished the most was my personal life, was my marriage and was my family. I always thought that it was one of my greatest accomplishments," he added.

Since the wedding ring is back on, does that mean Arnie's apologies have earned him a second chance? Guess we'll have to wait and see!
