Making the most of her time in Hawaii, Ashlee Simpson took her son Bronx to the beach for some sandy shenanigans yesterday afternoon (December 27).

Sporting a vintage Police band t-shirt and Ray Ban sunglasses, the “Pieces of Me” singer played with her adorable little boy (from her relationship with Pete Wentz) while photographers looked on.

Earlier in the day, Ms. Simpson teamed up with her mother Tina for some retail therapy at some of Oahu’s hottest boutiques.

Ashlee has been enjoying life as a single woman again after splitting up with her longtime boyfriend Vincent Piazza back in November.
