Miley Cyrus: I'm a Stoner No, wait, it's just a joke, says pal Kelly Osbourne By Mary Papenfuss, Newser User Posted Nov 28, 2011 12:25 AM CST 19 comments Comments Miley Cyrus gestures during a press conference near Manila last summer. (AP Photo/Aaron Favila) (Newser) – Goodbye innocence: The once-wholesome image of Miley Cyrus and alter ego Hannah Montana has apparently gone up in smoke. Cyrus is a "stoner," she quipped at her 19th birthday party after pals presented her with a Bob Marley cake. "You know you're a stoner when your friends make you a 'Bob Miley' cake," she laughed in a video obtained by the Daily. "You know you smoke way too much effing weed!' "I thought salvia was your problem," quipped BFF Kelly Osbourne, who threw the private LA bash for Cyrus last week. She was referring to the singer's explanation after her last birthday that the bong she was photographed with was only holding the legal herb salvia. But wait ... the weed part is all a joke, people, Osbourne later tweeted. "We started calling her Bob Miley as a JOKE! the cake was also A JOKE," Osbourne wrote.
