Jessica Simpson  was all smiles as she arrived at LAX this morning, and landed in NYC later today looking fresh-faced. Jessica wore all black  for the outing and had fiancé Eric Johnson and their daughter, Maxwell, close behind. Jessica is on the East Coast  to be a guest on the premiere episode of Katie Couric's new talk show, Katie, tomorrow. We'll also apparently see Jessica in her new Weight Watchers  ad, which is set to show sometime this week. Jessica has been working hard since the birth of Maxwell in May, meeting up with trainer Harley Pasternak and sticking to her Weight Watchers meal plan as she focuses on losing the baby weight. It looks like she's ready to show off all her efforts as she embarks on her first public appearance as a new mom.
