On the Speak Now single "Back To December," Swift apologizes (when does she ever do that?) to an ex for a rough night, a night that very well could have been the one when she dumped actor Taylor Lautner. Why assume she's talking about the former teen wolf, who first caught Swift's eye on the set of their "Valentine's Day" flick? Well, she referenced his "tan skin" and "sweet smile." The guy's both of those for sure.
