Hailee Steinfeld stole America's heart as tough little Mattie Ross in True Grit - but is she putting her heart AND lungs in jeopardy by taking up smoking?
Hailee was spotted in NYC on Tuesday puffing away on a cigarette!
What are you doing, gurl? This ain't no Ender's Game, it's your life!
Actually, Hailee is just getting her fake smoke on for her upcoming movie Ten Thousand Saints that she's filming with hottie Emile Hirsch.
Whew! We were worried for a second! Be as bad as you wanna be on film, Hailee!
Ch-ch-check out the pics (below) to see Hailee and Emile hard at work making it all look real!
