Ashlee Simpson and Pete Wentz took a walk around LA yesterday with their son, Bronx. With Bronx bundled in Ashlee's arms, the trio shopped and ran errands together. They're hanging out around home in California after a recent vacation to Hawaii, where Ashlee broke out her bikini to hit the beach. Ashlee has been able to enjoy nights out on the town with her sister, Jessica, but she's also looking forward to a Summer full of family-friendly fun. Pete's especially excited about taking Bronx to check out the big Summer blockbuster Toy Story 3.
