Forbes has come up with a new list of the 10 young women most likely to inherit their mega-rich fathers' fortunes - in short, the billion-heiresses of tomorrow. The final list does not merely represent the daughters of the world's richest men, however; for a true accounting, the magazine started with the daughters of the world's 150 richest people, all worth $6.4 billion or more, but then focused only on those with few or no siblings to divide the loot.

They further narrowed the field by disqualifying those with fathers like Bill Gates who have declared their intention to leave their fortunes to charity instead of their children. Also, they did not include those who have already inherited their money, like the world's richest woman, L'Oréal heiress Liliane Bettencourt.

No. 1 on the Forbes list is India's Vanisha Mittal Bhatia, daughter of Lakshmi Mittal, the fourth-richest person in the world with a fortune of $45 billion. The No. 2 and 3 heiresses are also the daughters of Indian tycoons, while No. 4 is Delphine Arnault-Gancia, daughter of LVMH chairman Bernard Arnault, the world's 13th-richest man with a fortune of $25.5 billion. And clocking in at No. 7 is championship equestrienne Georgina Bloomberg (above), daughter of New York's billionaire mayor Michael Bloomberg. See the gallery for more.
