One of the world's most famous couples is no more. Arnold Schwarzenegger and Maria Shriver have announced that they're "amicably separating," with the news breaking just two weeks after their 25th wedding anniversary and four months after Schwarzenegger left his job as California governor. Despite the unlikely union — with her Democratic roots and his Republican views — the news will still come as a shock to many. That said, Shriver wasn't wearing her wedding band in a recent video posted on YouTube.
