Jessica Simpson, Eric Johnson Make Their Way Through LAX Airport

Is it the hair? The boots? The trademark oversized bag? Either way, Jessica Simpson was looking better than ever as she made her way through LAX airport with fiancé Eric Johnson over the weekend. The 33-year-old mother of two -- she gave birth to boy Ace just three months ago -- wore a casual outfit of black leggings, black T-shirt and an oversized gray sweater, but still managed to look impossibly glamorous while doing so.

The couple were likely headed back from spending the weekend in Newport, Rhode Island, where Simpson served as the bridesmaid for her publicist Lauren Auslander's wedding Saturday. You can see a photo of Simpson walking down the aisle here.
