Dave Grohl and Taylor Swift beefing almost certainly was not on anybody’s 2024 bingo card.

So, why did Mr. Nice Guy call out the reigning princess of concert ticket sales?

Only time will tell.

Here’s how Dave Grohl and Taylor Swift’s friendly relationship seemingly turned sour.

You couldn’t make this stuff up.

As she saw it, the system didn’t provide fair royalties to artists.

“Piracy, file sharing and streaming have shrunk the numbers of paid album sales drastically …

Valuable things should be paid for,” Swift wrote forThe Wall Street Journal."

On paper, there doesn’t seem to be much artistic overlap.

And Grohl had nothing but praise for the pop megastar.

“I’m officially obsessed, she might want to get a restraining order.”

He reportedly dedicated three songs to Swift, including “Congregation” and “Best of You.”

A few years later, there were rumblings of a possible collab between Grohl and Swift.

However, he quickly set the record straight, tellingRolling Stonethat neither Swift nor Adele were on the album.

(The pop star was Justin Timberlake.)

Until Taylor Swift stepped in, that is.

“I’m like, ‘I don’t know how to play piano.

On top of that, Grohl had smoked some marijuana and was feeling the effects.

But then, another artist came to his rescue.

“All of a sudden, Taylor Swift stands up.

She’s like, ‘I’ll play a song,'” he said.

“Like f**king Batman when you need him.”

Swift hopped on the piano and Grohl, who is right-handed, grabbed one of McCartney’s left-handed guitars.

Eventually it clicked for him, and their impromptu duet was off to the races.

“She’s got a good voice, she can sing, man,” he said.

The message got a lot of attention, and not the good kind.

Of course, Violet is not the first person to say something online about Swift’s transportation choices.

For years, the “Are You Ready For It?”

Regardless, Violet’s post provoked the ire of many Swifties.

It seems like even the nicest guy in rock has his limits.

What’s more, the Foo Fighters frontman and Nirvana alum’s own supporters jumped into the fray.

A battle between fandoms exploded across social media, as videos of Dave’s remarks went viral.

It seems safe to assume he knows what he’s messing with.

One might think that it would be difficult for Swift to pencil in time for a feud.

As of this writing, Grohl hasn’t commented on Swift’s statement.

Hopefully, this bad blood doesn’t last too long.
