If you thought Taylor Swift and Ellen Pompeo were BFFs… think again.
The Grey's Anatomy star stopped by Jimmy Kimmel Live on Tuesday night and she revealed that her relationship with the 26-year-old singer is surprisingly cordial, despite the fact that Pompeo starred in Swift's "Bad Blood" music video.
"Her people called my people and said, 'Would you like to be in this video?'" the ABC star recalled. "And I said, 'Oh my god, of course, how fun! Is there an old lady section? I'm down.'"

When Kimmel asked if Pompeo now feels like a member of Swift's iconic "girl squad," the 46-year-old actress was quick with her response. "I do not," she said before adding with a laugh, "I do feel like I have the a** of a 20-year-old."
"Bad Blood" went on to win "Video of the Year" at the 2015 MTV Video Music Awards, but Pompeo has yet to retrieve her moonman award from Swift's place. "She so graciously invited me over to come and get it," the Grey's star said of Swift's moonman squad party in November. "I was working, so I still don’t have it. I do need to pick that up."

But there is another reason why Pompeo might be avoiding T-Swift's pad: Apparently she's "super allergic" to cats, which is a huge bummer considering Swift named her first cat "Meredith Grey" after Pompeo's on-screen alter ego.
"It's going to be very awkward," Pompeo said of the inevitable feline meet-and-greet.
