Mary-Kate Olsen and Olivier Sarkozy have taken their relationship to the next level.
The pair have only been dating since May but have become almost inseparable over recent months.
Olivier has now moved to downtown New York City to be even closer to Mary-Kate.
"They are really, really happy," a source told New York Post. "And Olivier is buying a townhouse below 14th Street, to be with Mary-Kate. We are told they're not officially moving in together - they both think it's too early for that. But he's telling friends that Mary-Kate is the best thing that has happened to him in a long time."
Olivier is the half-brother of former French President Nicolas Sarkozy. His relationship with multi-millionaire mogul Mary-Kate made headlines due to their 17-year age gap.
Despite their controversial coupling, the lovebirds seem happy with each other.
"Olsen and Sarkozy have just headed abroad for a romantic two-week vacation," the publication claims. "Shortly before they left town, Olsen was spotted shopping for clothing for the getaway at pricey lingerie boutique La Perla."
Insiders have previously revealed to US Weekly that Mary-Kate, 26, and Olivier have bonded over her business sense. Her extreme wealth often makes her appear older and wiser than her years.
"[She] is constantly complaining about boys not being mature enough for her. She got the kids out of her system," the insider told the publication.
