Dave Grohl of Foo Fighters performs at London Stadium
During his performance at the London Stadium on Saturday night, Foo Fighters frontman Dave Grohl took a dig at Taylor Swift, who was performing the second night of her Eras Tour at Wembley Stadium on the other side of the city.

During the concert, Grohl addressed the audience, jokingly referring to Swift, saying, “Let me tell you, you don’t want to be in the line of fire with Taylor Swift.” The comment prompted laughter and cheers from the crowd.
Grohl went on to compare the two tours. “That’s why we like to call our tour the Errors Tour. We’ve got more than a few eras, and more than a few bullshit errors. Just a few,” he said, joking about the name of Swift’s Eras Tour.
The Foo Fighters frontman then hinted that Swift’s performance might lack authenticity. “That’s because we actually perform live. What? Just saying. You guys love raw, live rock ‘n’ roll music, right? You’ve come to the right place,” Grohl said, further inciting the crowd.

This joke comes despite Grohl’s positive comments about Swift in the past. However, some fans speculate that the recent comment may be connected to an incident in which Grohl’s 17-year-old daughter faced online harassment from Swifties after she criticized Swift’s use of a private jet on social media.
During her third London show, Swift praised her live band and crew and highlighted their dedication. “Every single member of my band, every single member of our crew, my band that’s going to be performing live for you for 3.5 hours tonight, they deserve this so much,” Swift said. “And every single one of my fellow performers deserves this too. And you’ve given this to us so generously that we will never forget that.”

Swift’s London performances have been very successful, drawing around 80,000 fans each night. Following her London shows, Swift will perform in Dublin, Ireland, then continue her tour in Amsterdam, Switzerland, Germany and Italy, and will ultimately return to Wembley Stadium in August for five more shows.
