Hilary Duff Shares a Video of Her "Brave" Son Luca in the Ocean in Hawaii

Hilary Duff jetted off to Hawaii last week for a fun-filled vacation, proving once again that her bikini body just won't quit. The Younger actress, who is reportedly dating her trainer, Jason Walsh, was spotted having a ball while taking a dip in the ocean in Maui on Thursday. Dressed in an adorable two-piece swimsuit, Hilary flashed a smile (and her rock-hard abs) as she soaked up the tropical sun. She also took to Instagram to share precious family moments with her four-year-old son, Luca. In addition to the pair telling ghost stories, she also brought him out into the water on a paddleboard.
