Ashlee Simpson arrived at LAX yesterday with her mom, Tina, and a Louis Vuitton carry-on. It's a big weekend for the Simpson clan, as Jessica turns 30 on Saturday. She's been busy prepping for the milestone for a few weeks and just struck up a well-timed birthday romance. As the Simpson ladies made their way out of town, Ashlee's husband, Pete Wentz, and their son, Bronx, explored the trails at Tree People park. Pete's taking it easy with family since his departure from Fall Out Boy, and he recently announced that he's formed a new band called Black Cards.
