Lady Gaga smoked a joint while performing on stage in Amsterdam in September and she continued to show how much she loves to smoke by dressing up as marijuana  for Slutoween this year.

Gaga posted these pictures on her Little Monsters site and Tweeted: “So i was weed for halloween. BEST COSTUME EVER ITS SO FUN.”

The Gaga called herself "Princess High the Cannabis Queen". Gaga's weed smoking, possibly with Taylor Kinney (I have to blame men for everything), could be the reason why Gaga's gained weight recently only to lose it within days. SMH. And Gaga thinks she's a good role model.
