While performing at the London Stadium, he referred to Swift while she was playing the same night on the other side of the capital in Wembley - to boos from some fans.
He addressed the crowd: 'We were joking about the Taylor Swift tour earlier. I know that she's on her 'errors' tour.
'I tell you man, you don't want to suffer the wrath of Taylor Swift.
'So we like to call our tour the Errors Tour.

Addressing his fans at the London Stadium on Saturday night, Grohl said they were in the right place for 'raw live rock 'n' roll music'
'We've had more than a few eras, and more than a few f***ing errors as well. Just a couple.'
The band leader clarified: 'That's because we actually play live. What?'
To great cheers, he continued: 'Just saying. You guys like raw live rock 'n' roll music right?
'You came to the right f***ing place!'
Grohl and Swift have previously been on good terms, with the former praising the latter's decision to re-record her albums, reclaiming her back catalog.
Grohl also once spoke of how he was 'saved' by Swift after she assisted him while performing at a party held by Sir Paul McCartney.
Some users said Grohl's attack was motivated by abuse his daughter received from Swift fans after criticising the singer-songwriter for travelling by private jet
Some online users were unimpressed with Grohl's jibe at Swift, who has sold over 200million records worldwide.
One wrote: 'Oh Tayvoodoo is coming for him and he deserves it. Can't handle that a woman is more talented and successful.'
'Wow Grohl so washed he has to use Taylor's name for free pr? Embarrassing thought he was better than that what a shame', another user said.
Some fans suggested that Grohl's attack was partly fuelled by abuse faced by his daughter from Swifties - Taylor Swift's fans.
