OTRC: Mary-Kate Olsen, 25, dating Nicolas Sarkozy's 42-year-old brother Olivier, report says

Mary-Kate Olsen has been romantically linked to Olivier Sarkozy, the half-brother of former French president Nicolas Sarkozy.

The 25-year-old fashion designer has been linked to Sarkozy, a 42-year-old asset manager for a month. According to the New York Post, the pair spent Memorial Day weekend together in the Hamptons and are "head over heels" for each other. Olsen's rep had no immediate comment on the report.

Olsen dated New York artist Nate Lowman for two years before breaking up in 2010. She also dated Greek shipping heir Stavros Niarchos, before he started simultaneously dating Paris Hilton in 2005.

Sarkozy, who is the managing director of the Washington D.C.-based Carlyle Group, dated actress Stella Schnabel for a year before parting ways in March. He was previously married to writer Charlotte Sarkozy and has two children.

Mary-Kate and her twin sister Ashley Olsen began their acting careers when they were toddlers, playing Michelle Tanner on the sitcom "Full House," which ran between 1987 and 1995. They went on to star together in several films. Ashley Olsen's final acting role was in the 2004 movie "New York Minute," which also marked her last project she starred in with her twin.

The pair is now known for their fashion empire, which is made up of several clothing and accessory collections, such as the higher-end Elizabeth and James and The Row as well as Olsenboye for JC Penney. The twins are often seen at major fashion events and showcased their chic, personal styles. Vogue magazine named them the Best Dressed Siblings of 2011.

Mary-Kate Olsen's most recent acting role was in the 2011 movie "Beastly," a modern-day adaptation of "Beauty and the Beast," which saw her play a teenage witch alongside Vanessa Hudgens and Alex Pettyfer.

Meanwhile, their younger sister Elizabeth is drawing attention for her own acting performances. The 23-year-old starred in the 2011 film "Martha Marcy May Marlene" and in the recent horror film "Silent House."
