Taylor Swift is definitely a KatyCat.

After making a dramatic appearance on the 2024 MTV VMAs red carpet in a plaid corset ensemble, the “Fortnight” singer was caught getting down to Katy Perry’s Video Vanguard Award performance of hits on Wednesday night.

In a video circulating on social media, Swift was seen — after changing into a sparkly UFO mini-dress —enthusiastically dancing and singing to Perry’s chart-topping song “Teenage Dream” along with pal Suki Waterhouse.

It would seem there are still no hard feelings between the two music hitmakers who once famously clashed.

After Swift, 34, revealed her 2014 song “Bad Blood” was about another major star in the industry, fans speculated that the song was written about Perry.

The “Firework” singer, 39, addressed the rift in a 2017 interview on “The Late Late Show With James Corden,” claiming the feud was started by Swift.

At the time, sources told Page Six the problems started over John Mayer, who both women dated at different times.
