Slideshow:Ashton Kutcher Photo Gallery

Ashton Kutcher's fraternal twin brother Michael suffers from cerebral palsy. Wanting to help find a cure for the debilitating disease, he enrolled at the University of Iowa, majoring in biochemical engineering. Kutcher's wild partying days came to an end when a modeling scout spotted him at a local bar wanting to enter him in a local modeling contest. Ashton won the contest, which launched his modeling career. He soon crossed over into acting and has long since quit his partying ways, settling down into his family life with wife Demi Moore and his three stepchildren.
