Jessica Simpson stripped off her many layers to go through security at LAX today. She arrived at the airport wearing a hat, scarf, and sunglasses, and cracked a smile as she waited in line. Jessica is headed out of town again after just a few days back in LA following her most recent trip to NYC. When home in California, Jessica shared a lunch date with her sister, Ashlee, and mom, Tina, and while the Simpson girls were busy on the West Coast, Joe Simpson and Jessica's fiancé, Eric Johnson, had some fun of their own in Scotland. Joe and Eric apparently went golfing overseas, leaving Jessica and the rest of the crew home to enjoy their three-day break. Jessica wasn't spotted with the many other celebrities partying on Memorial Day, but she did have a sleepover with her adorable godson to kick off the long weekend.
