UPDATE:As speculated below, Mariska Hargitay did wind up in Taylor Swift’s “Bad Blood” video. Swift tweeted Harigtay’s character poster on Thursday afternoon, hours after announcing Ellen Pompeo’s involvement too.

So that means both of the women who gave Swift the inspiration for her cats’ names (Olivia Benson and Meredith Grey) are involved in this thing. Cool.

EARLIER: Now this is getting ridiculous: On Thursday, Taylor Swift revealed that in addition to pretty much everyone else in Hollywood, Ellen Pompeo will also appear in the video for “Bad Blood” as well.

Swift, of course, named one of her two cats Meredith Grey, after Pompeo’s Grey’s Anatomy character. The other cat’s name? Olivia Benson. So Mariska Hargitay should probably keep an eye on Swift’s Twitter feed throughout the day.

For all the other people in “Bad Blood,” head here. The video will debut on Sunday during the Billboard Music Awards.
