And it wasn't just any old ring - James had given her a vintage French platinum band along with intertwining diamonds.
According to ET, Bullock was taking a hike in Northern California last Friday when the picture was taken. She was seen drinking coffee and wearing a hat, with a scarf around her neck. The down-to-earth actress is keeping it real and was wearing barely any makeup. Her demeanor was somber despite the occasional smile.
Bullock's outdoorsy excursion marks the first time the actress has been seen out in public in over a month - after one of her husband's alleged mistresses, Michelle "Bomshell" McGee dropped the bomb about their steamy affair to In Touch Weekly.
