Jessica Simpson tweeted a picture of herself stepping out with daughter Maxwell Johnson, who was cuddled in her stroller, in LA on Friday. Jessica joked about the revealing photo of her chest, saying, "Just taking a walk around the block . . . Street legal???" Since giving birth to Maxwell in May, Jessica has been hitting the gym when she's not doting on her baby girl. Jessica signed a deal with Weight Watchers as she gets back to her pre-pregnancy figure, so fitness is top of mind for the new mum. Maxwell is still the most important part of Jessica's life, and she shared another sweet tweet about her little one, saying, "I absolutely LOVE my family! Maxwell amazes Eric and I every day with every little thing she does!"
