Hilary Duff Just Proved That Even Moms Can Have Killer Bikini Bodies

Hilary Duff might be a mom, but that doesn’t mean she can’t have a serious bikini body.

The 28-year-old proved she was ready for summer when she was spotted wearing a striped two-piece swimsuit while swimming off the coast of Hawaii this week.

The actress is vacationing with her ex-husband Mike Comrie and 3-year-old son in Maui. (RELATED: Hilary Duff Exercises Her Second Amendment Rights)
