Ashton Kutcher reflected recently on his eight-year marriage to Demi Moore and being a stepdad in his mid-20s to her three young girls. "I was 26, bearing the responsibility of an 8-year-old, a 10-year-old and a 12-year-old. That’s how some teen parents must experience their 20s," the "That '70s Show" star told Esquire in an interview published Tuesday.
