Billy Ray Cyrus took to Twitter on Friday to respond to the video that shows his daughter Miley Cyrus, 18, smoking out of a bong.
"I had no idea. Just saw this stuff for the first time myself," Billy Ray Tweeted. "I'm so sad. There is much beyond my control right now."
The video, which was first released on TMZ on Friday, shows Miley partying at her LA-area home on November 28. "Okay, I'm about to lose it now," Cyrus says after taking her first hit. "I'm having a little bit of a trip right now."
According to TMZ sources, the smoke inside the bong is a natural -- and legal -- herb called salvia, which has psychedelic qualities. (Possession of salvia is legal in California.)
The video was likely copied or stolen from Cyrus' friend's camera, TMZ adds.
