“Explosive Concert DRAMA: Dave Grohl Calls Out Taylor Swift You Don’t Want to Suffer Her Wrath!'”

Foo Fighters frontman Dave Grohl appeared to take a jab at Taylor Swift at the band’s concert on Saturday night at London Stadium.

After mentioning that Swift’s Eras Tour was currently taking place at London’s Wembley Stadium, Grohl said on stage, “I tell you, man, you don’t want to suffer the wrath of Taylor Swift.”

He continued: “So we like to call our tour the ‘Errors Tour.’ We’ve had more than a few eras, and more than a few fucking errors as well. Just a couple.”

Grohl then implied that Swift doesn’t perform live, telling the crowd, “That’s because we actually play live. What? Just saying. You guys like raw, live rock ‘n’ roll music, right? You came to the right fucking place.”

Grohl has praised Swift in the past and even dedicated the Foo Fighters song “Congregation” to the pop star at the BBC Radio Big 1 Weekend in 2015.

“I’m officially obsessed. She might want to get a restraining order because I’m all about Swift,” Grohl said at the 2015 U.K. music festival. “To my opening band, Taylor Swift. Taylor and the Swifts,” he added.

Swift is set to play the last date of her London stop on Sunday night at Wembley Stadium, though she will return in August for another five dates to end the European leg of the Eras Tour.

At her first London show on Friday night, Swift took a selfie with Prince William, who celebrated his 42nd birthday at the concert alongside children George and Charlotte.
