Taylor Swift and Mariska Hargitay’s friendship started with a cat connection, and after more than a decade, they are still the purr-fect pair.
Swift has been a fan of Hargitay’s long-running drama Law & Order: Special Victims Unit, in which the actress plays Detective Olivia Benson, for years. In June 2014, Swift paid homage to her favorite crime solver by naming her cat Olivia Benson. (Swift also has a feline named after Meredith Grey from Grey’s Anatomy and Benjamin Button, a nod to the 2008 Brad Pitt movie.)
“When she named her cat, I had so much going on,” Hargitay exclusively told Us Weekly in October 2014, noting she gifted Swift an engraved collar for the pet after learning of the name. “I was out of town, and when things calmed down, I thought it warranted a real something [special]. That’s so sweet and too fabulous.”
Nearly a decade later, Hargitay returned the favor by naming her pet Karma in November 2023 in honor of Swift’s hit song off her Midnights album.
“Are you serious?!!!! Nothing has ever come more full circle ⭕️ LOVE THIS SO MUCH!! 😻,” Swift wrote in the comments section of Hargitay’s kitten announcement in December 2023.

“My oldest son sang first, and he sang — well, he sang two songs — he sang ‘Blue Bayou’ by Linda Ronstadt, which is one of my favorite songs, and he also sang ‘Blue Christmas.’ It’s a little inside joke that we have,” she revealed. “Then, my daughter sang ‘Long Live’ by Taylor Swift.
