Shia LaBeouf Rolls a Cig For Rosie Huntington-Whiteley (PHOTOS)

Is Shia LaBeouf a model of chivalry, or what?

The Transformers 3 actor took a break from filming with his comely new co-star Rosie Huntington-Whiteley in Chicago over the weekend and, being a gentleman of impeccable manners, he busted out a pouch of tobacco and twisted up a smoke for his presumably nicotine-craving leading lady. (Hope he managed to control himself in her presence and didn’t slobber all over the thing.)

The Surgeon General might not approve, but you have to admire Shia’s gallantry, anyway.
