Robbie Williams recently spilled the tea about his surprise appearance during Taylor Swift's 2018 Reputation Tour at Wembley Stadium, and it's comedy gold. According to the cheeky British pop star, Swift barely knew who he was before stepping on stage - a claim that's both hilarious and slightly hard to believe. Williams claims Swift's then-boyfriend Joe Alwyn might have suggested bringing him on stage, joking that she only knew the "concept" of Robbie Williams. But when he emerged, the crowd's eruption left Swift stunned. "You could just see this thing in her face go, 'Eh!?" Williams quipped, adding with trademark swagger, "I'm the mayor of this here. I'm a big deal."

Fans of Robbie Williams songs will remember the iconic moment when he performed his smash hit "Angels" alongside Swift. The crowd's overwhelming response proved just how beloved the song remains. Swift herself seemed charmed, later writing on Instagram that the moment was "UNREAL" and "meant so much to so many people." Talk about a British invasion of pop royalty.
