Ashlee Simpson: Big Apple Stroll with Vincent Piazza & Bronx!

Ashlee Simpson and her beau Vincent Piazza hold onto little guy Bronx as the trio go for a stroll on Monday (July 23) in New York City.

The 27-year-old entertainer watched on as Vincent and Bronx, 3, danced with each other as they walked down the sidewalk. So cute!
