Whoa, When Did Ashton Kutcher Get So Buff?

The Ashton Kutcher of That 70s Show was the lanky, albeit gorgeous twink who would define our mental image of lanky, gorgeous twinks for years to come. Now, suddenly he's more muscle dad than pretty boy. What is going on?!

We hate to say it, but it seems like we have Ashton's upcoming role in the silly, vaguely misogynistic-looking romantic comedy "Killers" to thank for this incredible transformation. When we first caught a glimpse of these pics we were convinced that we were looking at a young Daniel Craig. Ashton's definitely gotten bigger since his run as Michael Kelso on that 70s show, but we never noticed quite how dramatic the change has been. Just look at the difference!

boy:

MAN:

In the film, Ashton plays an undercover government assassin who marries an unwitting (if not witless, ha!) Katherine Heigl. We can only assume that typically hilarious hijinks and a kind of action-packed adventure worthy of 10-20 lbs of muscle gain ensue. Added bonus: Now that our little pretty boy punk has bulked up a bit, maybe Demi will start letting him top?
