Millie Bobby Brown is the latest star to express their admiration for Taylor Swift.

On Wednesday, Brown stopped by The Kelly Clarkson Show, where host Kelly Clarkson lauded the Stranger Things and Damsel star’s “vast amount of success” despite being “only 20,” per Billboard. Brown eventually shared that she “feel[s] very excited to be 20,” likening it to “a new era, as Taylor Swift would say.”

After Clarkson asked if she attended Swift’s recent Eras Tour, Brown identified herself as a “hardcore Swiftie.”

“Like I know exactly where she is at all times,” she said, to which Clarkson teased, “Some might call that a stalker.”

Brown clarified that her comment was “loosely based,” and proceeded to describe Swift’s concert as “the most amazing experience.”

“The fans there are just so — they’re the same as me,” she gushed. “We love her that much.”

Brown also revealed that she and her sister even “have a board” to help them predict Swift’s trademark “surprise song at each show.”

“And we cross out the songs that she’s done, so we know which songs are left,” she began explaining, before asking somebody in the audience if they “do that too.”

She continued, “So that we know what she’s gonna do next.”

Brown, who said she flew to Ohio “solely for Taylor,” noted that Swift’s surprise song was her 2020 hit “Evermore.”

“And I collapsed to the ground,” she quipped. “It was pretty crazy.”

Brown is certainly not the only celeb to sing Swift’s praises. The View‘s Alyssa Farah Griffin proved she’s a fan of the pop phenom on Tuesday morning’s (March 5) episode by pointing out “a Taylor Swift reference” in Jason Kelce‘s NFL retirement speech

For Brown and Griffin’s fellow Swifties, Taylor Swift: The Eras Tour (Taylor’s Version) will be released on Disney+ on March 14, a whole day earlier than expected.

The Kelly Clarkson Show airs on weekdays. Check the website for local listings.
