Ashlee Simpson and Pete Wentz reunited yesterday in LA to spend a fun family afternoon with their young son Bronx. The trio visited the Travel Town Museum and evidently stopped off for pizza, as Pete later tweeted about burning his mouth on some hot cheese. Ashlee and Pete announced their plans to divorce in February, but have since been regularly photographed together with Bronx. They seem to be putting their differences aside for his sake, and Pete recently spoke about how they make it all work. Pete said of his split from Ashlee, "We try to make his life as easy to navigate as possible and he's growing up so it's important for everyone who loves him to be involved in his life. . . . He's a talker and he tells a lot of stories in full sentences." He and Ashlee are moving forward with their lives, as is her big sister Jessica. The Simpson family has something great to look forward to with Jessica's upcoming wedding, and she recently received even more good news — Jess was ranked as Us's Style Icon of the Year and also one of People's Most Beautiful Stars.
