That's exactly the situation that went down at Taylor Swift's house over the weekend.
On Sunday morning, Mariska Hargitay, who plays Olivia Benson on Law & Order: SVU, met up with Tay and her adorable pet cat, named after Mariska's of character. Luckily for us, the adorable moment was caught on tape for us to witness.
Tay actually posted a video of the legendary meet-up on her Instagram account. The real-life Liv also appeared in Taylor's "Bad Blood" music video.We know, we know...#friendshipgoals.
