Ashlee Simpson: Red Bull Break

Ashlee Simpson steps out with a friend before picking up her son, Bronx, from school on Tuesday (July 19) in Sherman Oaks, Calif.

The 26-year-old entertainer refueled with a can of Red Bull as she and her friend chatted.

Over the weekend, Bronx and his dad, Pete Wentz, went to Starbucks, where they ran into funnyman Tom Green on the way inside.

Ashlee was in NYC earlier in the month and was spotted smooching her new boyfriend, Vincent Piazza.

FYI: Ashlee is wearing an Alternative Apparel white burnout tank.
