17. Jessica Simpson
Jessica Simpson has had a whirlwind year — the star became a mother to a baby girl, Maxwell, with fiancé Eric Johnson in March. Jessica memorably confirmed her pregnancy by dressing as a mummy for Halloween and posting on Twitter that she planned to be a "mummy!" She proudly showed her bump in a nude cover for Elle and spoke candidly about her body's changes during her pregnancy. She and Eric always planned to wed following Maxwell's arrival.
Following the birth, Jess confirmed that she has a deal to lose her baby weight through Weight Watchers. Jessica also made the rounds to promote her reality TV series Fashion Star. Ever the entrepreneur, she's still managing her Jessica Simpson Collection and plans to branch out with a new maternity line in the coming months.
