Renowned for his chemistry with , Alexander has been delighting viewers for more than a decade, but turned heads in one shock encounter that left the normally cool legend red-faced.
The star previously had a frosty encounter in 2018 with Richard, who teased him over a story he told regarding Hugh Jackman.
Alexander asked the contestants a question surrounding the film industry, and as a result decided to take a delve into his own movie-making history – much to the bemusement of Richard.
One of the contestants answered Hugh Jackman after being asked to reveal who played Wolverine in the X-Men films.
After hearing the name, Alexander made a surprise confession about his connection to the star of film Logan.

He said: “He’s very nice, Hugh Jackman.”
Stunned by the remark, Richard responded: “Is he, I’ve heard that…”
Alexander then admitted that he and Jackman had starred in a Woody Allen film together, which left Richard smirking.
Pointing to the ground, Richard replied: “Sorry. You’ve just dropped a name there, by your podium. Have you got it?”

Realising that Richard was mocking him, he responded: “I’m just going to stand on it.”
The chatter then moved on to the film itself and the line Alexander was given in his role.
The line, Alexander revealed, was: “‘I’m just bringing the bodies out of the lake now sir.’”
But after retelling the line, Richard moaned that he wasn’t happy with his colleague’s delivery and argued it should have been played in a more “west-country” manner.
