Olivier Sarkozy net worth: Olivier Sarkozy is a French born investment banker for The Carlyle Group in New York City who has a net worth of $60 million. Olivier Sarkozy is the half brother of former French President Nicolas Sarkozy. The 42 year old Olivier has made headlines recently after he began dating 26 year old "Full House" actress Mary-Kate Olsen. The age difference is 17 years. Olivier Sarkozy earned his net worth as a Managing Director and co-head of Global Financial Services for asset management firm The Carlyle Group. The Carlyle Group, which has over $150 billion in funds under management, invests in a wide range of industries including real estate, retail, telecommunications, media, healthcare and more. Prior to joining The Carlyle Group, Sarkozy spent 11 years at investment bank Credit Suisse First Boston. He also worked at Swiss banking firm UBS from 2003 until he joined Carlyle in 2008. Sarkozy has a masters in medieval history from St. Andrews in Scotland. Olivier has two children ex-wife Charlotte Bernard. After the divorce, Ms. Bernard sold the couple's $12 million Upper East Side townhouse for a cut rate $8.4 million. Olivier has since moved into a $6.25 million townhouse of his own that he intends to share with girlfriend Mary-Kate. By the way, Mary-Kate's Olsen's $150 million net worth actually makes her $90 million richer than Sarkozy! In December 2013, Olivier Sarkozy and Mary-Kate sparked rumors that two might be getting married or even attempting to have a child in the near future. Despite being 17 years apart, the couple is not shy about appearing in public and loading each other up with generous PDAs. The couple has received their fair share of ribbing from the media over their age difference which many people say is hypocritical. Would this relationship be controversial if the gender roles were reversed? Today Mary-Kate and sister Ashley spend the majority of their time concentrated on their clothing line "The Row". They haven't retired from acting, but it apparently does not interest them as much as fashion and retail.
