Jessica Simpson covered her baby bump with a flowing maxi dress for a lunch outing with her fiancé, Eric Johnson, in Santa Monica, CA, today. The couple held hands for the day date, which comes as they prepare for the arrival of their second child this Summer. Jessica and Eric are already parents to their 1-year-old daughter, Maxwell, and Jessica recently expressed her wishes to tie the knot with Eric shortly after giving birth for a second time. She has been engaged to Eric since 2010, and she reportedly told friends that she wants to get married "a few months" after the baby is born. Jessica may be in the marriage mind-set since she was the guest of a pal's nuptials just last weekend. Jessica wore a tight black dress to attend the wedding of Kathryn Sykora and Chris Hetherington with Eric at the Rancho Bernardo Inn in San Diego, CA.
