Kate Hudson Flaunts Her Toned Abs During a Shirtless Ski Vacation With Her Sons

Kate Hudson escaped LA's Spring weather to enjoy the ultimate ski vacation in Aspen, CO, this week. The actress, who recently celebrated the release of her new book, has been treating her Instagram followers to snaps from her snow-filled trip featuring her sons, Ryder and Bingham, her brother, Oliver, and pal Sara Foster. On Wednesday, Kate shared a group photo of everyone shirtless on the slopes, writing, "Skis on, shirts off! #SpringSki," and from the looks of it, Kate's hard work at the gym has definitely paid off.

The last time we saw Kate's children was when they made their red carpet debut at the LA premiere of her movie Kung Fu Panda 3 back in January. Since then, she has gone on record saying that she has an "unusual" relationship with her son and that she'll never be a stay-at-home mom. Keep reading to see more of the family's snowy getaway, and then find out the workout habits behind Kate's enviable abs.
