The former "Hannah Montana" star celebrated turning 19 at a bash in Los Angeles, and pals presented her with a cake in the shape of pot-smoking reggae legend Bob Marley.
Cyrus, who was caught on film last year puffing on a bong, giggled, "You know you're a stoner when friends make you a Bob Marley cake -- you know you smoke way too much f-----' weed."
But a rep for the singer/actress tells "Access Hollywood," "The cake was a joke and Miley was being sarcastic. It is being completely taken out of context."
