Who cares, you may ask? Well, nobody really, except her husband and nearly 400,000 fans on Facebook. And all those people who thought even a smirk could only be a sign of the apocalypse.
David Beckham, the newly retired soccer star, took to Facebook on Sunday to share a really sweet photo of the typically expressionless fashionista, to whom he's been married since July 1999.
And boy, does she look happy.
"See I told you she smiles," he said, sharing the pic of his wife showing her pearly whites and almost winking.
"I actually used to smile a lot in pictures," the 39-year-old told Glamour in the September 2012 issue. "I think I only stopped smiling when I got into fashion.
"Fashion stole my smile! I've created this person. And I'm not saying that's not me, but I wouldn't say that's the whole me. It's an armor that goes up."
But some fans are thrilled to see her inscrutable face actually appear, well, scrutable.
We leave you with a few fan observations of this rare and glorious moment:
