Blake Lively Responds After Travis and Jason Kelce Watch “Sisterhood of the Traveling Pants” for the First Time

Lively posted a response to the brothers' notes about the titular pants in her 2005 coming-of-age movie

Blake Lively is giving props to Jason Kelce for his detective skills!

The actress responded to the former NFL player's review of her 2005 coming-of-age film The Sisterhood of the Traveling Pants on her Instagram Stories Friday, Oct. 18, calling him "a natural investigative journalist sniffing out the hidden truth."

Lively, 37, shared a clip of Jason, 36, and brother Travis Kelce's New Heights podcast, where they discussed the film. In Jason's case, he couldn't quite wrap his head around the "pants" aspect, as they "didn't have much to do with the plot."

As Lively explained in her Instagram Stories, the author of the book the movie is based on, Ann Brashares, shared with her and Lively and her castmates America Ferrera, Amber Tamblyn and Alexis Bledel "that she actually added the pants after the book was written because she was given the note to add a 'magical element.'

"Mind you, this is when Harry Potter hit, so everyone was looking for magic in youth books," Lively continued. "She used the pants as a tangible item to illustrate the sometimes inexplicable magic of the female bond. One that invisibly connects us, near or far."

"And there you have the Traveling Pants," she added. "Sisterhood of the Traveling Jeggings didn't quite hit. Now it would be Sisterhood of the Printed Jean Pajama Bottoms. I'm here for all."

The Sisterhood of the Traveling Pants starred Bledel, 43, as Lena, Tamblyn, 41, as Tibby, Ferrera, 40, as Carmen, and Lively as Bridget, four friends who remain connected by a shared pair of jeans as they go their separate ways for the first time one summer. A sequel dropped in 2008.

Speaking about Lively’s character in the movie, Jason and Travis, 35, agreed on their podcast that the actress “killed it” in her big film debut.

“She did absolutely wonderful as Bridget,” said Jason before Travis added, “Might have been a little biased, but I thought Bridget’s story was the most relatable and most fun.”

Jason also acknowledged that his wife, Kylie Kelce, had chided him for not realizing that the pants were symbolic.

"Kylie said, 'You idiot, it's a symbol that their friends are always with them, ' " the Monday Night Countdown analyst said.

Jason added that he would have preferred the pants have "magic powers," adding, "When they didn't and they were just a pair of jeggings that fit everyone's shape ... "

Still, the brothers agreed that the film was a powerful tale, with Jason saying, "It works and it does a great job of showing how people that struggle with those things have to cope ... I think we all can connect with these different characters."

"It's a good movie that ages well, I think, and that tells storylines that are important for women," he added.
