It's official: Mary-Kate Olsen is a married woman. The 29-year-old fashion designer and former "Full House" star married her French banker fiancé Olivier Sarkozy, according to Page Six.

The couple reportedly had an intimate ceremony Friday evening in Manhattan. The reception was held at a private residence on 49th Street, between Second and Third avenues, where all 50 guests were served cocktails in a rear garden before dining indoors. Both Olsen's and Sarkozy's parents attended the nuptials, Us Weekly reported.

Page Six claimed that guests were required to turn in their cell phone before entering the venue. The party décor reportedly consisted of "bowls and bowls filled with cigarettes, and everyone smoked the whole night," a source told the publication.

"It's gonna be a family thing," Mary-Kate and Ashley's sister Elizabeth Olsen told E! News about her family's plans for Thanksgiving. "Yeah, I'm really really excited and I've lived in New York for 8 years and I've left recently, so I'm really excited to go back and have some seasonal weather."

Olsen and Sarkozy, the half-brother of former French President Nicolas Sarkozy, started dating in 2012 and were engaged in 2014. He reportedly proposed to her with a 4-carat vintage Cartier diamond ring purchased for $81,250 at a Sotheby's auction.

"Mary-Kate is funny and sweet. Olivier's friends understand what he sees in her," a source close to Sarkozy told Us Weekly in February. While another insider close to Olsen said: "Mary-Kate's family thinks Olivier is the best thing to happen to her. They love him."

This is Olsen's first marriage. Sarkozy was previously married to Charlotte Bernard, with whom he shares two children - 13-year-old Julien and 11-year-old Margo.

The couple are living together in a $6.25 million townhouse in the city.
