Taylor Swift declined an offer from none other than Jennifer Lopez to make a cameo appearance in her documentary, The Greatest Love Story Never Told.

However, the official reason for rejecting this opportunity from the Anti-Hero songstress was not mentioned. Still, it can be speculated that her ongoing hit Eras Tour may have played a role in her decision.

In her documentary which was released on Tuesday, February 27, disclosed that Swift, 34, Jason Momoa, Jennifer Coolidge, Lizzo, Vanessa Hudgens, Ariana Grande, Snoop Dogg and Khloé Kardashian were unavailable for cameos in the project.

On declining the opportunity, Lopez didn't take it personally.

“I don’t wanna force anybody to do this who doesn’t go, ‘This is gonna be fun,’” she said in the documentary.

The Mother starlet added, “People are scared. Scared to put themselves out there. I get it. Took me a long time. I’m scared. I don’t act like I’m scared, but that’s the secret to my whole f–king career.”
