World's Richest Moms Here On Mother's Day

What do Tory Burch, Liliane Bettencourt, Gina Rinehart, and Sara Blakely have in common? They are just four of only 108 moms across the world who are also billionaires, according to Forbes. Not millionaires, BILLIONAIRES.

Here on Mother's Day, we salute the billionaire moms who are among the richest persons in the world but also dedicated moms.

Billionairess, Burch manufactures ballet flats, skirts and all manner of fashion. She is as high-profile in the fashion industry as one can get but when it comes to her children, the rules are different, she says.

"My children are off limits," Burch told the collection of high-powered women at the inaugural Forbes Women's Summit May 9th in New York. "My personal life is off-limits."

Believe it or not, raising nice, normal kids can be quite the challenge, even for billionaires. So too can be keeping your relationship with your children intact. What with the nannies, the media attention, and the abundance of wealth itself, billionaire spawn can face more than the average temptations by the time they reach 18, according to Forbes. 

According to Forbes, there are approximately 3,300 people in the world who have a father who is a billionaire but just 305 whose mom ranks among the world's super rich. Burch is one of less than two dozen who made their fortunes on their own and didn't inherit wealth from their fathers, grandfathers, husbands or moms.

Some of the better known mothers on our list include Spanx billionaire Sara Blakely, who has a young toddler to contend with as well as her $1 billion shapewear brand (she owns 100%, making her the youngest self-made woman on the Forbes rich list).

Laurene Powell Jobs, Steve Jobs' widow, has three children, the eldest of whom is now a senior at Stanford. Then there's HP CEO Meg Whitman, who made her fortune as CEO at eBay. Whitman's two boys attended Princeton just like she did, and she has described her children not as a detriment to her career, but the source of her inspiration, particularly during her failed bid for governor of California.  

Oprah, perhaps the most famous self-made female billionaire, doesn't have children of her own, but she did help raise Wendy, the daughter of her longtime partner Stedman Graham.
