Taylor Swift has packed even more stars into the A-list cast list for her "Bad Blood" music video.

On Thursday, she took to Twitter to announce that "Grey's Anatomy" star Ellen Pompeo will appear in the project, as "Luna."


Swift, of course, named one of her cats after Pompeo's "Grey's Anatomy" character, Meredith Grey. (The other is Olivia Benson, but there's been no sign of Mariska Hargitay -- not yet, at least.)

The singer also revealed "Bad Blood" posters for Jessica Alba, model Martha Hunt and "Empire" actress Serayah McNeill earlier this week:


Those three join a roster that includes previously-announced cameos from Karlie Kloss, Lena Dunham, Ellie Goulding, Kendrick Lamar, Gigi Hadid and Hailee Steinfeld. Is there anyone who isn't appearing in this thing?

The "Bad Blood" video will premiere Sunday night during the Billboard Music Awards.
