A video of Bobbi Christina hitting a three foot tall bong in 2011 has hit the internet.

Bobbi Kristina was apparently partying with friends who attend college in Georgia in 2011, when the video was taken.

A source said: "Bobbi Kristina was staying with friends at the school and she brought along a big bag of pot for the party. The party was well underway by the time I got there around 11 p.m. When I left at 6am the next day, she was still partying hard. Between tokes, Bobbi was drinking shots of Grey Goose and Skyy Blue vodka, and sipping a mixed vodka drink. She's obviously a seasoned partier.  With the amount of pot and alcohol she was using, I would have passed out."
