The So Yesterday singer seemed to be having a blast as she worked up a deep tan while on the ocean.The A Cinderella Story star paddled out like a pro on a long board and some snorkling gear.
The Cosmopolitan cover girl also took her son with her for a while. He wore a red cap and a life vest.
After a good hour of paddle boarding she was seen walking on the beach and collecting her things. On Monday she was seen perusing the aisles of Target with son.
Grabbing beach toys and board games, the singer pushed her cart through the store and to the parking lot.
Showing off he trim waist, Hilary wore a casual white t-shirt tucked into her jeans for the afternoon of shopping with Luca. Her distressed blue jeans were rolled up above her ankles with comfortable white shoes on her feet.
