(CBS) Miley Cyrus was caught on video calling herself as a "stoner," but her rep claims the singer was joking.
In the clip, obtained by The Daily, Cyrus alludes to being a fan of smoking marijuana after friend Kelly Osbourne presents her with a cake made to look like Bob Marley at her 19th birthday party last week.
"You know you're a stoner when friends make you a Bob Marley cake," she said. "You know you smoke way too much f***in' weed."
Osbourne then takes the microphone and jokes, "I thought salvia was your problem, Miley," a reference to Cyrus beinglast year smoking the legal herb, which can produce hallucinogenic effects.
A rep for Cyrus told People, "This is so ridiculous. The cake was a joke, and Miley was being sarcastic."
Osbourne also came to her friend's defense on Twitter, saying the incident was a joke.
"Let me make something very clear after @MileyCyrus salvia incident we started calling her bob miley as a JOKE!," she wrote on Sunday. "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!"
Osbourne added, "u guys if @MileyCyrus is not recording/filming/touring she is works everyday how could she possible do all that if she was a stoner! #think."
