If you have small kiddies who idolize Hannah Montana, you might want to ask them to leave the room!
This morning, a cell phone video leaked of Miley Cyrus celebrating just five days after her 18th birthday - with a bong!
Yes, there's actual evidence of Disney's most profitable princess taking a nice, good hit from a bong and getting high as a mother effing kite!
Aw, she's just being Miley! Nice friends you have, by the way! (We're told it was one of them who leaked this video!)
Also, the smoke billowing from the cylinder isn't coming from marijuana, but salvia - a legal "herb" in California with psychoactive properties, hence the gigglefest coming out of Miles!
Check out the video above to see a brand new side to Miz Miley!
And in case you're offended by this, let us remind you of one key point — SHE CAN'T BE TAMED!!!! Hah!
