Who's in the wrong amid the Kelly Clarkson bird dispute?

Kelly Clarkson has gone viral after claiming staff at a Brooklyn toy store refused to sell her a mechanical bird.

The store's co-owner has a very different version of events, and what followed was a messy back-and-forth involving review bombs, fan pile ons, and questions about whether the bird was ever actually for sale.

It's the kind of story that shouldn't matter, but somehow caught the world's attention.
