Ashlee Simpson and her son Bronx checked out his “favorite video game” Skylanders Trap Team at the Activision booth at the E3 Convention in Los Angeles last week.

Simpson, who is planning a very eclectic Bohemian theme Labor Day wedding to Evan Ross (son of Diana), took Bronx and two friends out of school early to be the first to get their hands on the  unreleased game (launches October 5th).

Bronx and Ashley were both big fans of the tomato throwing character, Food Fight and loved trapping the villains in to the “Traptanium Traps”.

Simpson and Ross will tie the know on August 31st at Diana Ross estate in Greenwich, Conn., during the evening, with white lanterns hanging from tree branches and outlining the walk way to the altar.

Simpson shares custody with ex-husband rocker Pete Wentz, who is expecting another baby with girlfriend Meagan Camper.
