Hayek, 57, also posted snaps with “Bridgerton” star Nicola Coughlan, Leslie Mann, Jonathan Van Ness and her 16-year-old daughter, Valentina.
Smear joined them in a VIP tent, where guests also included Swift’s boyfriend, Travis Kelce, and friend Cara Delevingne.
The night before, Smear played a Foo Fighters show at London Stadium, where Grohl, 55, insinuated Swift does not sing live on her blockbuster world tour.
“We were joking about the Taylor Swift tour earlier. I know that she’s on her Eras Tour,” Grohl told the audience, some of whom booed the “All Too Well” singer.
The band’s lead singer then added, “I’m telling you, man, you don’t want to suffer the wrath of Taylor Swift.
“So we like to call our tour the Errors Tour. We’ve had more than a few eras and more than a few f–king errors as well. Just a couple. That’s because we actually play live. What?”
He told his fans that if they like “raw live rock ‘n’ roll music,” they “came to the right f–king place.”
Swift seemingly responded to Grohl’s comment during her show Sunday when she assured the crowd that her entire set is performed live.
“What you just did is an unforgettable moment in not just my life, but every single one of our crew, the band that’s going to be playing live for you for three and a half hours tonight,” she said.
