The One Show viewers all seemed to be having the same epiphany just minutes into the programme when Barney Walsh joined his dad Bradley Walsh on the BBC show.
On Thursday's episode (December 19), the father-son duo promoted the revamped Gladiators, which is set for a celebrity special airing on New Year's Day.
However, many fans' attention was hijacked by a startling realisation: Barney Walsh and host Roman Kemp are, in fact, two distinct individuals. One bewildered viewer took to X (formerly Twitter) and confessed: "Seeing Roman Kemp and Barney Walsh on #theoneshow is strange to me. they both live in the same place in my brain."
Another chimed in: "My Nan will be having a moment right now seeing Barney and Roman in the same place at the same time. She thinks they are the same person, forever mixing them up."
A third onlooker tweeted: "Wait, Barney Walsh and Roman Kemp AREN'T the same person? " while another echoed, "I always thought Barney and Roman were the same person.", reports Wales Online.
