Hilary Duff, CEO

Is Hilary trying to be the next MK and Ashley? Under the brand Stuff by Duff, Hilary will be launching several products from clothing to home decor aimed at the Tween market. She just named herself Cheif Executive and Designer of her fashion and lifestyle company, and hired the Olsens' former manager to lead her merchandise empire. Pretty ambitious of Ms Duff.

This fall you can find Hilary's Stuff at stores such as Wal-Mart and Target. Good luck to Hilary. MK and Ashley are a tough act to follow. Not so sure about this one, although the tween market does seem to be on fire.
