Jessica Simpson's Baby Bump: The Sequel! Keeping things much more casual than fellow pregnant star Kim Kardashian, the 32-year-old singer and Fashion Star mentor ran some low-key errands in Los Angeles on Thursday, March 28. Wearing minimal makeup and sunglasses, with her blonde hair down, Simpson hit the gym wearing a snug black tank top that emphasized her expanding belly plus a black hooded sweatshirt, white, rolled-up sweatpants and sneakers. The style mogul also hit a local Chanel store for some retail therapy.

As Simpson and fiance Eric Johnson await the arrival of their second child, a boy, later this year, they're also enjoying watching their firstborn, 11-month-old daughter Maxwell Drew, grow up -- and so is everyone else! Last weekend, Maxwell accompanied her mom and her aunt Ashlee Simpson for a trip to Charlotte, NC, where Jessica and Ashlee, 28, greeted fans and customers at a Jessica Simpson Girl's Collection event.

With her blonde hair and blue eyes, little Maxwell stole the show -- and reached out for a hug! -- as her mom and aunt signed autographs and posed for photos.

"Jessica was in an amazing mood," an observer told Us Weekly of the event, adding that proud papa Johnson, 34, was also on hand. "Eric was very attentive, making sure that she feels fine . . . Ashlee was having fun, too."
