The Olsen Twins & The Michalka Sisters

Two talented blonde sisters with hot style and family TV roots. What a winning formula! At least for The Olsen Twins and Aly & AJ. With their stint on Full House and collection of kid-friendly videos and products, Ashley and Mary-Kate became pint-sized phenoms! And if Aly and AJ Michalka have anything to do with it, they hope to be just like the Olsens: "Mary-Kate and Ashley are definitely inspiring -- you know, to look at the empire they built," says AJ. Like MK and Ashley, Aly and her sis were a TV success (Haversham Hall and Cow Belles), and are developing their own fashion line, too! No word yet on what they'll call it (the Olsens' line is The Row) but it's gonna debut early next year.
