Martha Stewart has an important memo for all of the septuagenarians out there: Sexting is cool, okay? During an appearance on Ellen Wednesday morning with her cooking buddy Snoop Dogg and The Accountant star Anna Kendrick, the trio participated in the classic horny party game “Never Have I Ever,†with Stewart divulging that she has, indeed, done a bit of sexting here and there. Just don’t ask her to talk about it: Stewart lamented that it was none of Ellen’s business when she asked for the sultry deets. Hey, the woman’s known for her topless Christmases, after all.
