Ruh roh! Kristen Stewart, the brooding young starlet currently playing Bella in the chaste, religiousy teen vampire romance movie Twilight, was photographed brazenly smoking the devil's herb on the front steps of her Los Angeles home earlier this week. In the middle of the day! Tsk tsk. I guess we now know why she was so out of it on Letterman the other day. But, I suppose it's just a little pot and it'll be OK and she'll go back to work on the sequels and earn her ridiculous $12 million. As long as there's no boy-related funny business... down there.
