Olivia Benson and Meredith Grey may be TV characters, but to Taylor Swift they’re so much more. They’re the names she chose for her cats. No wonder the “Blank Space” singer was so excited to see a shout out to her on a selfie of Mariska Hargitay and Ellen Pompeo–the actors who play the aforementioned characters.

Olivia Benson is, of course, the lead detective on Law & Order: SVU. Ellen Pompeo played Meredith Grey on Grey’s Anatomy. The two actors posed for a selfie after running into one another at the Super Bowl on Sunday, and posted it to Mariska Hargitay’s Instagram account.

“This one goes out to @TaylorSwift13 @taylorswift #CatsOutOfTheBag #NFL #NationalFelineLeague #MeowMeow #CatsMeow,” Hargitay captioned the photo.

Taylor Swift was beyond excited to see Olivia Benson and Meredith Grey in the same photo.

This isn’t the first time that Mariska Hargitay has reached out to Taylor Swift via social media either. Back in September, she shared another selfie–this one solo–and in it she wore a cat collar that featured a little charm engraved ‘Olivia Benson.’

Hargitay captioned that photo, “@taylorswift this came in the mail #WrongAddress #GotThisByCatccident #DontHaveACatniption #Collared #GonnaWearItAnyway #CatsOuttaTheBag #MeowliviaBenson #ScratchThat #PurrrfectName #TaylorMade #3MonthsLater #ALittleLateToThePawty #ThisCollarNeedsACat #PawAndOrder #OliviaBensonPetDetective.”

Do you suppose Taylor Swift had any idea when she named her cats Olivia Benson and Meredith Grey that the characters who portray those roles would take notice and interact with her this way?

Kudos to both Mariska Hargitay and Ellen Pompeo for having such great senses of humor and fun.
