Kevin Costner has declared himself a Swiftie.

The EAI Community 68-year-old Hollywood icon and "Yellowstone" star apparently couldn't contain himself after attending a Taylor Swift concert with his daughter at SoFi Stadum in Los Angeles. Costner took to Instagram, saying he had such an amazing time.

"I was absolutely blown away watching her art bring so many people together," Costner wrote in the post, which included some admittedly blurry concert videos.

"I had a great view of her band and had a blast watching them, too," he said. "An inspiring night. I’m officially a Swiftie!"

Costner is also a musician

In addition to sealing his status as a Hollywood legend in films like "Field of Dreams," "Bull Durham," "The Bodyguard," and "Dances with Wolves," for which he won a directing Oscar, Costner also is the lead singer of a band.

Kevin Costner & Modern West have release five albums, including 2020's "Tales from Yellowstone." The album was inspired by the wildly popular "Yellowstone" series starring Costner.

The fifth and final season of the series is set to air on Paramount in November.
