London: Miley Cyrus` father Billy Ray has admitted he has been left bitterly disappointed over a video which surfaced online showing his teen star daughter smoking a bong.
The country singer, who is in the throes of a divorce from wife Tish, took to Twitter today to address the tape, which captures the 18-year-old giggling uncontrollably after puffing on the pipe with friends, reported a daily.
"Sorry guys. I had no idea. I`m so sad. There is much beyond my control right now," he posted.
The video was shot at the `Hannah Montana` star`s home near Los Angeles, California, five days after she turned 18 on November 23.
But sources insist the pipe wasn`t filled with marijuana. Instead, she is said to have been smoking salvia, a powerful hallucinogenic herb.
It is legally available for sale in California – where the video was shot - and in other states in America.
It is reported that the clip was shot by a friend, but later stolen.
