There was some equestrian fun going on on the Olympic field today, but who could concentrate with Kate and William in the stands -- and in Gucci sunglasses, no less? The duke and duchess, along with the Duchess of Cornwall, Prince Harry, Princess Eugenie and Princess Beatrice, attended the Eventing Cross Country Equestrian event on the third day of the 2012 Olympics, cheering on their cousin Zara Phillips.

It was Zara's first Olympic equestrian eventing competition this year and supposedly she did quite well. The AP reports that Phillips, granddaughter of Queen Elizabeth II, rode the course in nine minutes, 55.11 seconds, "well under the 10-minute, 3-second time limit" -- which sounds pretty good to us. (Although can you imagine if she bombed?)

In any case, Catherine and William seemed pretty pleased. The duchess entered the stands looking sharp in her navy blazer (seemingly the same one she wore with those infamous coral skinny jeans), her white Olympics polo and navy wedges. William also had on his Olympics polo shirt.

But really, it was the shiny sunglasses that stole the show. We only get a glimpse of Kate in sunnies every so often and we can't recall seeing Prince William in shades in ages. We were slightly disappointed: both royals picked a somewhat dated style, flashy shades that recalled the early aughts. But they look so darn cute together we'll give 'em a pass.

Check out the stylin' royals gazing into each other's sunglasses with not a care in the world.
