Yeah, it was pretty cool to see," Shelton said.The 23-year-old American, currently ranked No. 6 in men's singles, subsequently touched on his conversation with his tour guide in Basel. According to Ben Shelton, the guide acknowledged Roger Federer's celebrity status in Switzerland but hilariously said that the people of the country don't see anyone else hailing from it as a celebrity."I was asking the guy who was giving the tour, 'so here in Switzerland is Roger the biggest celebrity?' He was like, 'oh yeah', and I was like, 'Who's number two?' and he's like, 'no one'. I was like, 'oh, okay.'," the American added.Ben Shelton made fascinating Roger Federer admission at Wimbledon 2025Ben Shelton during a press conference at the 2025 French Open (Source: Getty)At this year's Wimbledon Championships, Ben Shelton made an impressive run to the quarterfinals before eventually exiting the prestigious grass Major following a loss to eventual champion Jannik Sinner.
