Naturally, that was our first thought when we happened to catch Anne Hathaway out and about the Big Apple today with what appears to be a cast on her right arm.
So what happened?
Well, that's a very good question.
E! News has yet to hear back from the star's rep with a possible explanation.
Fortunately though, the actress is also sporting a smile along with that sling, so whatever the reason, hopefully it isn't too bad!
