Ashton Kutcher – best known for playing adorably dimwitted characters in “That ‘70s Show” (FOX, 1998-2006) and “Dude, Where’s My Car?” (2000) or making Justin Timberlake believe his house was getting repossessed on one of his successful reality show creations – made his mark both onscreen and off, creating characters and television programs that appealed to the masses. But nothing he did onscreen raised more eyebrows or his public profile than his relationship and marriage to Demi Moore, an A-list actress and mother of three girls close to his age who just happened to be 15 years his senior.
