Jessica Simpson tweeted a picture of herself stepping out with daughter Maxwell Johnson, who was cuddled in her stroller, in LA on Friday. On Thursday, Jess was spotted heading to the gym in a slightly more covered-up look. 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 prepregnancy figure, so fitness is top of mind for the new mom. 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!"

Whitney Port hit the pool with friends in Miami yesterday. The girls were together for a bachelorette party, and maid of honor Whitney shared a picture of herself with the bride in their bikinis. Today the girls enjoyed time on the beach together. Whitney has been busy with her red-carpet appearances, fashion line Whitney Eve, and work on Britain & Ireland's Next Top Model. She still made time for this getaway to celebrate with one of her best girlfriends, and they all looked to be enjoying their afternoons in the warm weather, despite bouts of rain. Whitney will be joining the ranks of celebrity bridesmaids when the wedding takes place later this Summer.
