Their relationship has been branded 'grotesque' by critics.
But Mary Kate Olsen, 26, and Olivier Sarkozy, 42, are doing their best to prove their haters wrong by packing on the PDAs at a basketball game.
The couple, who have been together nine months, seemed closer than ever at the Dallas Mavericks versus New York Knicks game at Madison Square Garden on Saturday.
Despite a 16 year age gap between them the pair have shrugged off any insinuation their romance won't last.
At the game it seemed difficult for the pair to tear their eyes off each other with Mary Kate opting for a casual look, with rough hair and a hoodie.
Meanwhile Sarkozy's ex-wife Charlotte, whom he divorced last year, has branded his relationship with Olsen as 'grotesque'.
Yet by all appearances, the cavalier half-brother of former French president, Nicolas Sarkozy isn't concerned with the criticism.
Meanwhile, dating older men seems to run in the family for the pint-sized uber-rich actresses-turned-fashion designers.
Mary-Kate’s twin sister Ashley Olsen was 21 when she dated biking super star Lance Armstrong who was 36 at the time - a 15 year age difference.
Olivier is divorced and has two children with his ex-wife Charlotte, and he is the managing director of the Washington, D.C. based Carlyle Group.
Mary-Kate also has a history of dating high profile men.
She was linked romantically to Heath Ledger before his death and dated Greek shipping heir and Paris Hilton's ex Stavros Niarchos.
