Liliane Bettencourt (France) $20 billion

87. Widowed, 1 child

Makeup heiress inherited fortune from her father, the founder of cosmetic giant L'Oreal. Europe's richest mom is not on speaking terms with her only daughter, Fran?oise Bettencourt-Meyer. Daughter claims Fran?ois-Marie Banier, 61, a well-known photographer, writer and painter Liliane befriended, took advantage of her mother, who became a widow in 2007. Last year Bettencourt-Meyers petitioned courts to investigate reported $1.4 billion worth of cash and gifts that her mother allegedly gave Banier. Liliane denies all; has been ordered to undergo psychological testing before a July trial.
