Miley Cyrus a 'stoner'?

Miley Cyrus branded herself a “stoner” at her birthday party.

The 19-year-old star joked that she smokes “way too much weed” slang for marijuana when her pals presented with a Bob Marley birthday cake at the bash at Beacher’s Madhouse inside the Roosevelt Hotel in Los Angeles last Tuesday.

In a video obtained by website The Daily, she is seen saying, “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!”

Alluding to an incident last year when footage emerged of Miley smoking a bong water pipe which she later claimed contained the legal hallucinogen Salvia, her pal Kelly Osbourne replied, “I thought salvia was your problem!”

A spokesperson for the former Hannah Montana star has denied she was referring to her own drug use in the video.

“It’s all been taken out of context. The cake was a joke and Miley’s response was intended to be sarcastic,” said the rep.

Kelly who organized the bash for her friend later took to her twitter page to defend the comments in the clip and slam the person who leaked the footage.

“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,” she wrote.

“It makes me sick that @Miley Cyrus so called ‘friends’ would sell her out and lead people 2 believe she is someone that she is not!

“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.’ (sic)”
