2. Taylor Swift and Katy Perry
Both Taylor Swift and Katy Perry are notoriously famous people who hated each other and their feud continues to date. It is not only that they have expressed anger at each other, Swift’s song Bad Blood is about Katy Perry and supposedly the latter went as far as trying to sabotage one of Swift’s performances. Interestingly they were both close friends before becoming sworn enemies of each other. The personal feud continued for years before it became public. Both women ended up dating the same man at some point in their lives. Right before her album 1989 released, Swift spoke about the awkward friendship that she had with Katy and from there on the world saw the two squabbling.
