One million, billion points for Gryffindor, Hermoine Granger.
Ch-ch-check out the incredible video (above) and if you want, you can read her entire speech HERE.
Update: Kristen's publicist claims that the video was illegally shot on private property, hence we have removed the clip from the site.
We know she has an affinity for smoking the green stuff - and was caught by the paparazzi toking up in front of her house - and now virginal Bella has been caught yet again doing something she shouldn't by the paps!
Kristen Stewart, who just turned 19 years old in April, was shooting the shit and unwinding with some coworkers at an on-set party after a long day of filming her new Runaways biopic. And while she didn't bring her peace pipe, K-Stew is clearly seen drinking a Heineken.
Ooops, someone should tell the movie star that the legal age to drink beer and liquor in America is 21.
It's a good thing K-Stew is not a role model! She's not, right???
Watch her boozing video (above)!!!
P.S. Stewart also didn't buckle up in the car after they drove off at the very end of the video.
Breaking more laws!!!!!
