Wild rumor of the day: Paul McCartney will appear on AMC’s Mad Men in a cameo.

The UK paper The Sun reported the music legend is in talks to appear on the show’s fifth season. “It’s perfect timing because his new music suits the program perfectly,” an anonymous source told the publication, which ran a story headlined “Sir Paul McCartney will have a cameo role on hit TV show Mad Men.” “Action in the show has now reached the Swinging Sixties. So it’s only right that the man who was pivotal to the era is involved in the show.”

Sources close to the show insist there’s no truth to it. Though McCartney is a huge name, the stunt casting would be rather distracting and off-brand for a drama that prides itself on avoiding gimmicks. (Plus it would just be weird: McCartney playing another character on a period drama when Young Paul and The Beatles were at their peak).

A Mad Men source added, however, “Sir Paul is welcome to stop by any time as he’s beloved by the show as he is everywhere around the world.”
