Martha Stewart, 81, graces Sports Illustrated Swimsuit cover and makes history as its oldest model

Martha Stewart has made history as the oldest Sports Illustrated Swimsuit cover model ever on Monday. 

Stewart, the longtime author, lifestyle expert and 81-year-old media personality, reflected on the distinction. 

"When I heard that I was going to be on the cover of Sports Illustrated Swimsuit, I thought, Oh, that's pretty good, I'm going to be the oldest person I think ever on a cover of Sports Illustrated," Stewart told the magazine. "And I don't think about age very much, but I thought that this is kind of historic."
