Now, I know he's Canadian and probably has had little sun exposure, but seriously, Michael Cera seems incapable of aging past 15 1/2 years old. According to some sources, Michael is 21 years old, but it's simply not believable. Perhaps he is holding out so he can play young George Michael if the Arrested Development movie ever gets made. Maybe some studio executives put him up to this so he could corner the awkward tween market for life. OR maybe he's just drinking the same kool-aid as his semi-girlfriend Charlyne Yi (from that god awful Paper Heart movie.) Regardless, George Michael has got some 'splaining to do. Whatever he's doing works and needs to be marketed to aging women immediately.
