Tallulah Willis shared a photo of herself hanging in the pool with her sister Scout and their mom, Demi Moore [1]. The snap, which Tallulah posted on Father's Day [2] with the caption, "When you can't be with the papa. . . #mymomsbodtho," shows the 52-year-old posing in a printed two-piece [3] and basically looking half her age. Though oldest daughter Rumer was missing from the fun, we did get to see her and Demi twinning it up in a social media photo just last month; they stood side by side wearing matching glasses and jumpsuits [4] on Memorial Day. Check out Demi's banging bikini body, then see more stars in sexy swimwear here [5].
