The “Sports Illustrated” Swimsuit Issue has several covers this year . . . and one of them features 81-year-old Martha Stewart.  She’s wearing a one-piece bathing suit with a severely plunging neckline.  And she looks GREAT.

Martha did a little prep for the shoot.  She says, quote,

“I didn’t starve myself, but I didn’t eat any bread or pasta for a couple months.  I went to Pilates every other day. I live a clean life anyway.  Good diet and good exercise and healthy skincare can do all that stuff, but it was kind of fun.”

She adds, quote, “To be on the cover [at] my age was a challenge, and I think I met the challenge.”

Martha is one of FOUR cover models this year.  The others are Megan Fox, model Brooks Nader, and trans singer Kim Petras. Check out galleries of all four ladies here.
