9. Taylor Swift And Calvin Harris
This has to be the easiest choice. These two perform all around the world and have no free time to build a relationship. Taylor Swift is currently in America’s Midwest on tour while Calvin Harris is doing his thing in Vegas. Long distance relationships are impossible for us regular people, so that makes it doubly impossible for two of the biggest celebrities in the world. To be honest, Taylor Swift coupled with anybody would have made it on the list.
