Taylor Swift and Katy Perry are two of the biggest names in pop music, and rank amongst the most famous women in the world. The duo are idolized by tweens, teens, and their parents, all of whom flock to their concerts and sing gleefully along with each singer's mountain of hits.
Their shared history with John Mayer aside, Swift and Perry also may be among the best liked female celebrities, not just with the public but with their peers. Each singer seems to have as many friends as they do music videos. Heck, they're even friendly with each other, with Perry once stopping by a Swift concert to sing Hot N Cold. With most of the world wanting to hang out with either Swift or Perry, we ask the question... who would you rather have as a BFF?
