Mary-Kate and Ashley Olsen have topped the Young Hollywood's Top-Earning Stars list compiled by Forbes.com. The 20-year-old twins, who rose to fame in ABC sitcom Full House, pocketed US$40 million last year from their retail empire, making them the richest under-21s in showbiz.

The young business moguls actresses are reportedly worth around ?300 million thanks to their "tween" merchandise, clothing line and movies.

Harry Potter star Daniel Radcliffe, 17, who earned an estimated ?13 million for his lead role in Harry Potter and the Order of the Phoenix which is due out later this year, came second.
