Fortune has just released their 40 Richest Under 40 list, and this year's list has a large number of celebrities, though as in previous years, IT money has clearly made young millionaires and billionaires out of a large number of the ranks. In addition to the list itself (readers can access the entire list through the button on the left-hand-side of the page), the feature includes stories on the increasing wealth of celebrities, female stars, the richest and boldest newcomers to the list, and Fortune's methodology in compiling the data.
