Ashley Olsen approves of her twin sister's unlikely romance with Olivier Sarkozy.

The pint-sized fashion designer 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 on Saturday. 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.

According to city documents filed on September 10, Olivier purchased the 5-story love nest on August 2 after selling his previous property for $6.25 million in February.
