With her tongue sticking out, the Younger actress, 27, worked a boob-flaunting striped triangle top with cat-eye sunglasses and, so perfect for summer, a pineapple beverage. While she didn't use text to caption the pic, she did use a string of seasonally appropriate emojis, including a peace sign, an octopus, a sun, and the featured fruit.
On the beauty front, Duff, who shares one son, Luca, 3, with ex-husband Mike Comrie, modeled crystal-clear skin and a casually slicked-back 'do.
The sexy selfie is a change of pace for the Lizzie McGuire alum, who's been sharing a slew of sweet Luca-centric pics lately. Three of her previous four Instagram posts have featured a shout-out to the little boy, including one fun quote post reading, "Pants? You mean leg prisons," which she captioned, "Luca's daily struggle."
