Taylor Swift toyed with the fabric of the universe over the weekend, introducing her cat Olivia Benson to the "real" Olivia Benson.

On Saturday in Philadelphia, Swift's fan-favorite kitty got to meet Mariska Hargitay, the actress who has been portraying the "Law & Order: SVU" detective since Swift was 9.

"This is Olivia Benson meeting Olivia Benson, and, um, things are going well so far," the now-25-year-old said in an Instagram video showing the cat tentatively meeting the Golden Globe winner.

No animals or long-running dramas appear to have been harmed during the making of the video. The space-time continuum also appears to be intact.

Hargitay and Cara Delevingne -- who both had cameos in Swift's "Bad Blood" music video -- joined the singer onstage during the song "Style" at the second of two shows in Philly. Previous runway companions on the "1989" world tour have included Gigi Hadid, model Martha Hunt and Echosmith's Sydney Sierota are among those who've done the honors.

“Couldn’t even contain my happiness because @caradelevingne and @therealmariskahargitay surprised the crowd tonight,” Swift tweeted.

Hargitay was pretty stoked herself, telling the "Shake It Off" singer on Sunday morning, "So honored to share the catwalk with you! And so tempted to hop on the tour bus... #UntilNextTime."

Next time for Swift will be Friday in Germany. She'll hit L.A.'s Staples Center for six shows running Aug. 21-26.
