Ashlee Simpson's Son Bronx is Growing Up Before Our Eyes!

Ashlee Simpson poses for a photo with her five-year-old son Bronx while stopping by the Activision booth at the E3 Convention on Monday (June 10) in Los Angeles.

The mother-son duo checked out Bronx‘s “favorite video game” Skylanders Trap Team and were able to be the first to get their hands on the unreleased game. He is growing up so fast!
