Miley Cyrus made a startling confession when she was presented with a Bob Marley cake at a party to celebrate her 19th birthday last week. Looking at the cake, she commented, “You know you’re a stoner when your friends make you a Bob Marley cake. You know you smoke way too much f**king weed!” The incident was captured on video and released on the Internet. Kelly Osbourne, who hosted the event, joked, “I thought salvia was your problem!” Kelly was refering to an incident that took place last year when Miley was captured on camera smoking out of a bong. The former Disney star denied she was smoking marijuana, claiming instead it was salvia, which is legal in California.
