"It was the last major event I covered with Matt Lauer, the greatest partner anyone could ever have," says Vieira, whose final broadcast of Today aired Wednesday. "He was complaining about how he wasn't into the wedding at all...couldn't see what the big deal was. But as Prince William and Princess Catherine were driving through the crowds in their Aston Martin after the marriage ceremony, I thought I saw Matt start to tear up. I commented how it had finally gotten to him and without missing a beat he said, 'It's not the wedding, it's that car!' "
