Jon Hamm, former Mad Men star, admitted to claims about his penis that he is well endowed and frequently goes without underwear. Hamm told Australia's GQ magazine: "It was a topic of fascination for other people, certainly not me...By the way, as rumours go, not the worst." The 45-year-old actor has previously slammed speculations about his genitals as "rude" and insisted some fans had gone too far in their interest in his "privates".
