In case you didn't already know, one of Taylor Swift's adorable cats is named after Mariska Hargitay's "Law & Order: SVU" character, Olivia Benson. Well the two have finally met! Cat Olivia Benson met the REAL Olivia Benson backstage at Taylor's recent concert ... and it was purr-fect (#sorrynotsorry we couldn't resist the cat pun).

Taylor said during the video, "This is Olivia Benson meeting Olivia Benson and, um, things are going well so far." 

T-Swift brought out Mariska and Cara Delevingne -- who both made an appearance in Tay's "Bad Blood" music video as "Justice" and "Mother Chucker" respectively -- to walk the catwalk during her performance of "Style." The actress had a blast on stage and even gave her and Taylor a new nickname: Tayriska. A few of Hargitay's Instagram posts from the night featured the hashtag #Tayriska (we are SO on board with this).

Get you #Tayriska fill below with videos and photos from the show:
