Hilary Duff has abs for days!
The "Lizzie McGuire" alum showed off her hot bod and washboard abs while hitting the beach in a printed string bikini over the Labor Day holiday weekend in Kihei, Hawaii.
The mother-of-one was joined by her adorable 3-year-old son, Luca, and a girlfriend as they were spotted playing in the water and soaking up the sun together.
Clearly, all that time in the gym has been paying off -- we've never seen the actress look better!
Duff opened up about her post-baby bod while promoting her new show, "Younger," earlier this year, where she admitted that dieting is a struggle for her.
"I'm the worst dieter ever so I don't have the best body, but I'm proud of my body and I'm, like, accepting of what it is," she told E! on the red carpet.
"I'm not ever going to be 110 pounds again, so working with what you got and just trying to feel strong and powerful I think is a good motto for a mom who's 27," she added.
Hilary must be either extremely modest -- or blind -- because she's got one of the best beach bods around, if you ask us!
