Ashley Olsen approves of Mary-Kate`s boyfriend

London: Actress-fashion designer Ashley Oslen approves of her twin sister Mary-Kate`s unlikely romance with much older boyfriend Olivier Sarkozy.

Ashley was spotted tagging along for a lunch date with her sister Mary-Kate and 42-year-old Olivier, the half-brother of former French President Nicolas Sarkozy, in New York City, reported Contactmusic.

The group was seen dining at upscale Italian eatery Sant Ambroeus in the city`s trendy West Village.

The 25-year-old former ‘Weeds’ actress has been dating French-American banker Olivier for almost seven months and the couple are rumoured to have officially moved in to his plush new East Village townhouse together recently.

Olivier purchased the 5-story love nest on August 2 after selling his previous property for 5.2 million pounds in February.

"They are really, really happy. He`s telling friends that Mary-Kate is the best thing that has happened to him in a long time," a source said.

Mary-Kate previously dated artist Nate Lowman for over two year before splitting in 2010, while Olivier romanced actress Stella Schnabel for a year before their break-up in March.

Olivier was previously married to wife Charlotte and they have two children together.

Charlotte has since called the new romance "grotesque" and "not right".
