This is something we don't see very often!
Mary-Kate Olsen and hubby Olivier Sarkozy enjoyed a romantic (and rare) date night in NYC last night. The super-private couple held hands and posed for pics while attending the "Take Home A Nude" annual auction at Sotheby's.
Olsen wore a long black coat dress and white shoes while her hubby looked dapper in a gray suit, shit and tie.
But Olsen and Sarkozy aren't the only surprising celeb couple on our radar today.
