An official announcement has yet to be made by the Academy of Motion Picture Arts & Sciences either confirming or denying Crystal as host, and there's a chance Crystal was just joshing with his adoring public. (But what kind of dick move would that be?) So take it as you will, and start getting used to the fact that no, the Muppets probably won't be hosting the biggest night in Hollywood. At least, not this year.

UPDATE: The L.A. Times' Steven Zeitchik Tweets confirmation: "Crystal's tweet may or may have not been a joke. But we've confirmed with a source close to telecast. It's Crystal."
