Nothin' gets those vocal chords warmed up like a hit from a joint.

While rehearsing for her Art Basel performance in Miami yesterday (Dec. 3), Miley Cyrus -- donning hot pink pigtail extensions and a baseball tee emblazoned with a drawing of boobs -- was photographed smoking a blunt on stage.

Of course, this is not shocking behavior for Miss Miley -- who pretty much openly declares her love of marijuana every chance she gets -- but we are a little surprised that she'd smoke anything (even if it is just a cigarette) before hitting the stage to perform. That being said, the 'Wrecking Ball' singer doesn't seem to mind -- just check out that happy-go-lucky grin on her face.

See the pictures of Miley smoking below.
