Taylor Swift has hilarious reaction to Katy Perry kissing a female performer on VMA stage

Taylor Swift had a hilarious reaction during one moment from Katy Perry's VMA Video Vanguard performance.

The 'Teenage Dream' singer accepted a lifetime achievement award tonight at the MTV Video Music Awards and performed a collection of some of the biggest hits throughout her career.

At one point during the setlist, Perry performed one of her newer tracks 'I'm His, He's Mine' featuring rapper Doechii.

The duo got up close and personal during the song's choreography and shared a kiss on stage.

While fans watching evidently lost it, it seemed that Swift also joined them in the frenzy.

In footage captured by an audience POV camera pointed at Swift, the singer could be seen dancing along before abruptly stopping to watch Perry and Doechii kiss in shock.

She proceeds to turn around and start laughing before joining the audience in cheering and applauding the two performers.

After losing it over Perry's iconic performance, fans are now equally losing it over Swift's reaction, with one user on Twitter writing: "Even she was GAGGED."

While another wrote: "She had our reaction."

"She's so real for this." a third user added.

Meanwhile, Perry accepted her Vanguard award and gave a touching speech on her career and all the lessons she's learned.

"Thank you so much to MTV for believing in my weirdness from day one, and for helping artists extend their worlds beyond a song. There are so many things that have to align to have a long and successful career as an artist. There are no decade-long accidents," Perry began.

"I’m excited when I look around music today and I see all the amazing young artists who are operating with confidence, agency, vulnerability and authenticity.

"I’ve heard a lot of do this, don’t do that, wear less, wear more now, don’t cut your hair… one of the biggest reasons I’m standing here right now is I learned how to block out all the noise, that every single artist in this industry has to constantly fight against, especially women.

"I just want to say with my whole heart, do whatever it takes to stay true to yourself and true to your art, turn off social media, safeguard your mental health, pause, touch grass, and do what you were born to do, just like I was born to do this."
