Miley Cyrus Posts Picture of Herself Smoking Marijuana

Not exactly the breakfast of champions, eh?

Miley Cyrus found herself in hot water — or more precisely, hot air — when the ex-Disney star posted what appeared to be a picture of herself smoking a large marijuana joint on her Instagram account.  Whatever ambiguity the picture left, the caption cleared right up:  "High as f---."

It's unclear what prompted the sudden honesty from Cyrus, 20, who was the subject of much controversy back in November 2011 when a video filmed at her 19th birthday showed Cyrus being presented with a Bob Marley birthday cake. "You know you're a stoner when your friends make you a Bob Marley cake. You know you smoke way too much f---ing weed," she said in the video.

At the time, close friend Kelly Osbourne, who also appeared in the video, quickly came to Cyrus' defense and claimed that Cyrus' stoner comment was part of an inside joke. "You guys, if Miley is not recording/filming/touring, she works every day," Osbourne tweeted. "How could she possibly do all that if she was a stoner! #think" A few months later, Cyrus was photographed coming out of a medical marijuana facility in California with a friend.
