That’s insane!’ Blake Lively was left speechless by a ‘silly question’ about her best friend and godmother to her children, Taylor Swift. In an interview on Australian TV show The Project…

Blake Lively was at a loss for words over an “insane” question about her bestie Taylor Swift.

During an appearance on the Australian TV show “The Project” Tuesday, the “Gossip Girl” alum was asked to pick one of the 14-time Grammy winner’s songs to “soundtrack her life.”

“You can’t ask me to pick one song,” she responded. “That’s a wild question.”

Blake Lively, pictured above on “The Project” Tuesday alongside actress Jenny Slate, was at a loss for words after being asked a question about Taylor Swift.

The “Gossip Girl” alum, seen above with Swift, was asked to choose one of the 14-time Grammy winner’s songs to “soundtrack her life.”

Honestly, I love her music too much to pick one song. That’s just, like, insane. … I can tell you my favorite child sooner if you would like to know that,” Lively, 36, continued.

“I’m joking. I genuinely don’t have a favorite child or song.”

The actress and her husband, Ryan Reynolds, have maintained a close-knit relationship with Swift, 34, since 2015, and the pop star is the godmother of their children: James, 9, Inez, 7, Betty, 4, and Olin, 1.

Lively continued, “Honestly, I love her music too much to pick one song. That’s just, like, insane. … I can tell you my favorite child sooner if you would like to know that.”

Recently, the “Deadpool” star, 47, joked that the “Lover” songstress was also his kids’s nanny — with a hefty hourly charge.

“The cost of that is … I believe the accountant said, ‘Cost-prohibitive,” he quipped during an interview with “E! News” last month.

“But I think what he meant was, ‘Cost-insane-what-are-you-doing-I’m-no-longer-you’re-accountant.’”

In the past year, Lively and Reynolds have been spotted out with Swift in New York City and at Kansas City Chiefs games in support of the singer’s boyfriend, Travis Kelce.

They recently jetted to Spain to watch Swift take the stage for her Eras Tour concert alongside their three eldest children.

Swift gave a special shout-out to the little ones before performing her “Folklore” album, which notably has several nods to the A-list couple’s daughters.

I have to say that on ‘Folklore,’ some of my favorite characters are named James, Inez and Betty,” the “Love Story” performer said.

While Lively and Reynolds did not reveal the name of their youngest child until last month, the “Proposal” star previously joked that they had been waiting for Swift to drop a song with their son’s moniker.

“We always wait for Taylor to tell us what the child’s name is,” the actor said on the “Today” show in May. “And I’ll say this: We’re still waiting.”
