The celebs have been chiming in on their tweets over the death of Bin Laden but it was Dwayne "The Rock" Johnson who managed to tweet 45 min. BEFORE the President made his announcement!  Either he has a direct line to the Pres. or he has friends on the other side of the globe who filled him in.  Johnson's tweet: "Just got word that will shock the world-Land of the free...home of the brave...PROUD TO BE AN AMERICAN!"  Here are a  few other celeb tweets below:
