Miley Cyrus' father Billy Ray has taken to his Twitter.com blog to express his disappointment at the teenage superstar after she was caught on camera smoking a bong.
The Hannah Montana star, who turned 18 last month, was filmed puffing on a huge pipe allegedly containing hallucinogenic legal high Salvia days after celebrating her birthday.
In the video, obtained by TMZ.com, the singer/actress is seen inhaling huge lungfuls of smoke, reportedly from the burning of controversial but legal psychoactive plant Salvia.
The clip has caused a stir online and her entertainer dad Billy Ray has now waded into the controversy, apologizing to fans for Miley's behavior.
Taking to his Twitter blog on Friday, he writes, "Sorry guys. I had no idea. Just saw this stuff for the first time myself. Im so sad. There is much beyond my control right now."
Billy Ray Cyrus split from Miley's mother, Tish, in October.
