Mary-Kate Olsen Heads Home With Rumored Fiancé Olivier Sarkozy After Lunch Out in New York

No glimpse of the 27-year-old fashionista's diamond ring this time—but that's only because she was photographed

Home, sweet home for Mary-Kate Olsen and Olivier Sarkozy.

The 27-year-old fashionista and her 44-year-old banker beau, who is now reportedly her fiancé, grabbed lunch in New York City on Saturday afternoon, after which they were spotted returning to the presumably pretty-fancy-inside townhouse they share in Manhattan.

Alas, paparazzi only got Olsen from the right side, so while we got a glimpse of an enormous emerald-green cocktail ring she was wearing on that hand, there was no sighting this time of the vintage Cartier diamond she's been rocking on her wedding finger.

The former child star looked her usual chic self in ankle-cropped trousers, a black pea coat and black loafers sans socks.

Olsen has yet to address the reports that she and Sarkozy are planning to tie the knot, much like little sister Elizabeth Olsen, who according to multiple outlets is now engaged to her boyfriend, Boyd Holbrook.

Meanwhile, it was twin Ashley Olsen by Mary-Kate's side at Paris Fashion Week and then last week the CFDA Award nominees attended the launch of two new fragrances by their Elizabeth & James line, Nirvana Black and Nirvana White, at a Sephora in NYC.

The Council of Fashion Designers of America has nominated The Row, another one of the sisters' luxury brands, for Accessories Designer of the Year.

A source has told E! News that Olsen is looking to "marry and settle down as quickly as possible," while Sarkozy, a divorced father of two, is on the side of a long engagement.

Olsen was first linked to the half-brother of former French president Nicolas Sarkozy around May 2012 when they were spotted looking cozy at a New York Knicks game. Countless Knicks games later, Madison Square Garden remains a reliable place to spot the kiss-cam-ready duo.

Sources told E! News in December that the increasingly serious couple were considering marriage and that Olsen was "crazy for Olivier." However, the insider added, Sarkozy was also recently divorced and didn't seem to be in a rush to remarry.

But sometimes love just wins in the end. Vive l'amour.
