The only reason we can think of that prevented Taylor Swift from suing the dude back in 2013 when the whole thing took place is that she wanted to stay classy and forget all about it.
Okay, we need to backtrack a bit with this one.
Namely, in 2013, Taylor did a gig in Denver and she was joined backstage by a local radio DJ called David Mueller who asked for a pic with the famous pop star. While they were posing, he allegedly grabbed Swift’s behind. He was fired sometime later and he claimed that it was all because Taylor falsely accused him of grabbing her. Moreover, he sued Taylor.
His story changed a bit over time and Taylor finally got fed up with the whole thing. She is now counter-suing the ass-grabber.
Finally!
