Twin moguls MARY-KATE and ASHLEE OLSEN have set their business sights on a new target - boys.

After successfully attracting hordes of young female fans to their various branded products, the 19-year-old sisters have decided it's time the opposite sex enjoyed their merchandise.

Ashley says, "My sister and I started the whole 'tween empire. I definitely see the potential for boys to do that sort of thing."

The Olsens' Dualstar Entertainment Group has signed 13-year-old twins COLE and Dylan Sprouse as the combined face for a new line of DVDs, CDs, sporting goods and clothing - as well as video games and mobile phone downloads.

The Sprouses' resume includes stints on sitcom Friends and roles in Adam Sandler comedy Big Daddy.

The line is set to launch next year (06).
