We're not 100% sure about this one, but we do know that during Swift's October 2012 appearance on "The Ellen DeGeneres Show," Ellen flashed photos of various men whom Swift had been spotted with (and a few others), trying to figure out who inspired Swift's track "We Are Never (Ever) Getting Back Together." When "Glee" star Cory Monteith popped up, Swift went red in the face, big time. Swift and Monteith were rumored to be dating in 2010.
