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.

Swift was in the audience as the Perry brought the crowd to its feet with a medley of her greatest hits Wednesday night.

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.

“Honestly, it’s really like she started it, and it’s time for her to finish it,” Perry said at the time, adding that she attempted to talk but failed to resolve their issues.

“It was a full shutdown and then she writes a song about me, and I’m like, ‘OK, cool, cool, cool, that’s how you want to deal with it? Karma!’”

In June 2019, the “Lifetimes” songstress revealed the pair had finally squashed their beef by sharing a picture on Instagram of a tray of cookies, with the words “peace at last” written in frosting on top.

Swift attended this year’s awards show without NFL boyfriend Travis Kelce as her arm candy since the Kansas City Chiefs tight end was due in Missouri for practice.

The team is set to play their second game of the season against the Cincinnati Bengals Arrowhead Stadium on Sunday.

It’s unclear whether the 14-time Grammy winner will attend Kelce’s upcoming game, though she was on hand for the team’s season opener against the Baltimore Ravens last week.
