Taylor Swift was on Ellen and completely mortified when Ellen displayed pictures of her with a handful of exes including Taylor Lautner, John Mayer, Joe Jonas, Cory Monteith and a few others. 

Ellen tried to get her to reveal who her songs are about, but Taylor refused saying it's "the one shred of dignity" she has left. 

Check out the video of Taylor on The Ellen Show.

Below is the "Begin Again" video.
