Watch Taylor Swift’s ‘stunned’ reaction to James Kennedy’s ‘Cruel Summer’ remix at Coachella

That’s not (Taylor’s Version).

Taylor Swift hilariously reacted to James Kennedy remixing her hit song “Cruel Summer” during his Neon Carnival afterparty set at Coachella on Saturday.

The pop star, 34, was caught “jamming out” to her own tune like “every Swiftie” in a TikTok video — only to act “stunned” when she noticed a shift in the song.

Swift promptly stopped singing before glancing sharply over her shoulder.

“The way she looks at us like Jim in ‘The Office,’” one social media user joked of Swift’s exaggerated response.

A second fan claimed, “It’s giving if I wanted it that way I would have made it that way.”

Bravo fans gushed in the comments section over their “worlds colliding,” with some hoping that the “Vanderpump Rules” star’s girlfriend, Ally Lewber, had seen the footage.

Neither Kennedy, 32, nor Lewber, 28, have yet to react to the viral video of Swift.

The reality star has documented his DJ career on the show over the years, telling viewers in 2020 that he was “work[ing] toward” one day performing at Coachella.

Swift, who is on a brief break from her record-breaking Eras Tour, has never taken the stage at the music festival and attended this weekend as a fan.

She and boyfriend Travis Kelce made headlines for their PDA-packed behavior in the crowd.

Not only were the duo caught on camera dancing, with the NFL player even lifting the Grammy winner into the air at one point, but they also made out during the Neon Carnival bash.

Swift and the athlete kicked off their weekend with a dinner date and were photographed holding hands outside Sushi Park.

The couple have been spending a ton of time together during Kelce’s NFL offseason, from a Bahamas vacation to a stint in California.

They are planning on getting engaged this summer, a source told Page Six in January.
