Blake Lively is one of Taylor Swift ’s best friends and biggest fans, but don’t ask her to pick a favorite song. “You can’t ask me to pick one song. That’s a wild question,” Lively, 36, said during a Tuesday, August 6, interview on Australian TV show The Project .

“Honestly, I love her music too much to pick one song. I could tell you my favorite child sooner if you would like to know that answer.” The Gossip Girl alum went on to confirm that she “genuinely” doesn’t have a favorite child — or a favorite Swift song.

Lively and her It Ends With Us costar Jenny Slate appeared on The Project ahead of the premiere of their new film , which hits theaters Friday, August 9. Based on the Colleen Hoover novel of the same name, the Justin Baldoni –directed film uses Swift’s “My Tears Ricochet” in the official trailer. The song comes from Swift’s eighth studio album, Folklore , and aligns with Hoover’s tale of domestic violence, with Swift singing from the perspective of a spirit speaking to her murderer.

“Colleen is able to tell something that’s deeply personal and intimate but is able to resonate with so many people,” Lively said at a Q&A for Book Bonanza. “And Taylor, she’s such an incredible writer. She writes from such personal experiences and vulnerability.

” Lively went further by comparing the author to the songwriter, referring to them as “women who are authoring their stories.” Lively and Swift’s friendship expands far beyond.
