Roger Federer Shows Off His Stack of Friendship Bracelets as He Enjoys Taylor Swift's Eras Tour with His Family

Roger Federer is a Swiftie!

The tennis pro, 42, was spotted with his wife Mirka and all four of their kids — twin girls Myla and Charlene, 15, and twin boys Leo and Lenny, 10 — at Taylor Swift's Eras Tour stop in Zürick, Switzerland on Monday, July 8. The proud dad then showed off the dozens of friendship bracelets stacked on his wrist on his Instagram Stories the next day.

An Eras Tour fan account on X shared a snap of the couple smiling with their arms around each other in the crowd, alongside Federer's picture of his bracelet stack. "🚨| Roger Federer attended Night 1 of Taylor Swift's 'The Eras Tour' in Zürich, Switzerland!" #ZurichTSTheErasTour," captioned the post.

"We went to a lot of concerts last year," he said, noting that it was so fun to get on stage with Coldplay at their Zürich show last summer.

"I didn't sing, I just played a little shaker thing," he said with a laugh. "But we also saw [Bruce] Springsteen twice, and Elton John. This summer Taylor Swift is coming to Switzerland so of course we'll go to that, and ACDC too."
