Jessica Simpson confirmed her pregnancy earlier today by tweeting a picture of her mummy Halloween costume, and now she's sharing even more from their festive shoot! Jessica posted more pictures of her tight, baby-bump-baring getup alongside Eric Johnson as classic Celtics star Larry Bird. Eric is from the Boston area, so the team must be close to his heart. Even their dog, Bentley, got in the spooky spirit with a fun pearl leash and collar. The designer had two big announcements today as she finally revealed that she is expecting, and this morning Jessica launched her new venture BeautyMint. Just think, next Halloween Jessica and Eric will be out trick-or-treating with their son or daughter — congrats to the growing family!
