While filming "So Undercover" in New Orleans during winter 2010, Miley became close friends with Kelly Osbourne. In fact, Kelly threw her a birthday party for her 19th birthday at the Roosevelt Hotel in Los Angeles. When the birthday girl was presented with the cake, which was shaped like Bob Marley, Miley exclaimed, "You know you're a stoner when friends make you a Bob Marley cake -- you know you smoke way too much f------ weed." Kelly then said, "I thought salvia was your problem!" Video of the exchange was leaked online, and the media pounced. Quick to do damage control, Kelly took to Twitter and wrote, "Let me make something very clear after @MileyCyrus salvia incident we started calling her bob miley as a JOKE! the cake was also A JOKE! it makes me sick that @MileyCyrus' so called 'friends' would sell her out and lead people 2 believe she is someone that she is not!"
