Stars -- times two! From beloved blonde duo Mary-Kate and Ashley Olsen, to Scarlett Johansson and her hunky twin brother, Hunter, see which famous stars have the twin chromosome!
Ashton Kutcher and Michael Kutcher
"I consider him my best friend," Michael Kutcher said of his fraternal twin to a group of high school students back in February 2012. Michael, who was born minutes after his fraternal twin, was diagnosed with cerebral palsy as a child. "Being Ashton Kutcher's brother, it gives me the opportunity to be that voice, and I realize that I needed to use the opportunity to help others," he told the Hill in 2010.
