Hilary Duff ’s blood, sweat and tears have proven worth it as her impressive abs were on display during her beach holiday.

The 28-year-old looked fantastic in a multi-coloured striped bikini, showing off her toned physique.

Strong is definitely the new skinny if Hilary is anything to go by, as her beach body was on point as she had fun with her son Luca and ex-husband Mike Comrie on their sunshine break in Hawaii.

Hilary was certainly a far-cry from what someone who has just got a divorce looks like.

The former couple sealed the deal on their divorce - two years after their split - on Tuesday, according to Us Weekly, but as family they looked a picture of happiness. More photos
