Nicolas Sarkozy's brother Olivier Sarkozy has moved on from Stella Schnabel and is now dating Mary-Kate Olsen.
Sources said the former French president's 42-year-old younger half-brother, who is the managing director of the Carlyle Group, has been seeing 25-year-old Olsen for about a month, and they are "head over heels" for one another.
The couple was spotted in the Hamptons over Memorial Day weekend.
Olsen dated artist Nate Lowman for two years until splitting in 2010. Divorced Olivier dated Schnabel, a poet and actress, for more than a year before they parted in March.
