The beef between Katy Perry and Taylor Swift

Amid reconciling, some fans are still not convinced that the two pop superstars fully reconciled. For that, the feud between them resurfaced, stating how their silent brawl went on for years.

However, Katy shared that what she had with Taylor is a misunderstanding. "What I'm so grateful for is we did get to make up publicly and got to be an example of redemption for young girls," she added.

A year after releasing Swish Swish in 2017, the 36-year-old mother-of-one graced the music video of Taylor's You Need To Calm Down, as she offered reconciliation cookies. After the matter, Taylor gifted Katy a baby gift in September, and reports of the two artists made headlines that they are distant relatives, per Billboard.
