Taylor Swift may be basking in a whole new personal era, but it didn’t stop her from alluding to a longtime feud with Kim Kardashian during the Eras Tour Saturday.

The Grammy winner, 34, used the second of three consecutive nights at London’s Wembley Stadium to debut “thanK you aIMee” — the first of two surprise songs at the show.

“We get to play Wembley Stadium eight times this summer,” she told the crowd. “When I’m thinking about that, you think about just being grateful and being thankful. On the other hand, it really makes me think about how every time somebody talks s—t, it just makes me work even harder.”

The capitalized letters in the title spell out the SKIMS founder’s first name.

In her new album, “The Tortured Poets Department,” the track refers to a hometown bully who ultimately triggered Swift’s gratitude for the success that pain pushed her toward: “But when I count the scars, there’s a moment of truth / that there wouldn’t be this if there hadn’t been you.”

“I’ve never played this one before. Wish me luck,” Swift told the crowd ahead of the performance.

Swift and Kardashian’s feud dates back to 2016, when the reality star’s then-husband Kanye West used his song, “Famous,” to slam the pop star, saying he “made that b–ch famous.” The lyric was never cleared by Swift, according to her camp.

Kardashian, now 43, then released an edited video of a phone call between Swift and the rapper, now 47, making it seem as though the “cardigan” singer gave him the green light.

Shortly after “TTPD” dropped in April, a source told People Kardashian is “over it and thinks Taylor should move on.”

Swift’s beau Travis Kelce was the other big star of the night, as he bonded in the stands with Tom Cruise, photos obtained by TMZ showed. Cruise, 61 — who was nowhere to be seen at estranged daughter Suri’s graduation Friday at LaGuardia High School in New York — was also snapped swapping friendship bracelets with fellow Swifties — a tradition of the Eras Tour — before the show began.

Hugh Grant, who was in the crowd Saturday, tweeted his praise for Swift’s “incredible show” and “amazing and v[ery] hospitable team,” and praised her “excellent if gigantic boyfriend (#tequilashots).”

Swift and the Super Bowl champ, also 34, went Instagram official earlier in the weekend with a selfie, in which they were beaming on either side of birthday boy Prince William, as well as his eldest kids, Prince George and Princess Charlotte.

Swift announced last week the Eras Tour, the first concert tour to ever gross $1 billion, will end in December.
