Hilary Duff and her BF did some hardcore beach combing down in Mexico … with minimal clothing, muchas gracias.
In case you forgot … Jason Walsh made sure everyone in Puerto Vallarta knew he’s a personal trainer by flexing through their day on the beach.
The couple looked to be searching for sea shells or something, but mostly bikini-clad Hilary just found an eyeful of his ass. Fun day, indeed.
