For nearly four decades now, Johnny Depp has been the definition of Hollywood cool, bringing his own iconic style to life on the small screen (in "21 Jump Street"), in cult faves like "Ed Wood" and "Fear and Loathing in Las Vegas," and in big-screen smashes like "Sleepy Hollow," "Charlie and the Chocolate Factory" and, of course, the "Pirates of the Caribbean" franchise.

So, in recognition of his achievements — and all that classic cool — Depp will be honored with the MTV Generation award at the 2012 MTV Movie Awards, broadcasting live on Sunday, June 3 at 9 p.m. ET from the Gibson Amphitheatre in Universal City, California.

And as part of the celebration, dynamic duo the Black Keys will perform a special rendition of their hit "Gold on the Ceiling" in Depp's honor.

The MTV Generation Award is the Movie Awards' highest honor, acknowledging an actor who can be counted on to engage the MTV audience with everything he or she does ... previous recipients include Reese Witherspoon, Sandra Bullock, Ben Stiller, Adam Sandler, Mike Myers, Tom Cruise and Jim Carrey.

Depp's honor is just the latest addition to what is shaping up to be a very big show indeed. "Bridesmaids" and "The Hunger Games" enter the Movie Awards as the night's most-nominated films, comedian Russell Brand will serve as host, the Black Keys, Wiz Khalifa, Fun. and Martin Solveig are set to perform ... and as if all of that weren't enough, fans will also get an exclusive look at footage from this summer's most anticipated film, "The Dark Knight Rises."
