Mary-Kate Olsen smokes in front of boyfriend Olivier Sarkozy’s young daughter

Yahoo! OMG

Mary-Kate Olsen may be a billionaire, but money can’t buy her class. After grabbing dinner with her new boyfriend, Olivier Sarkozy, and his young daughter Margot in New York City over the weekend, the child star-turned-fashion mogul lit up a cigarette and puffed away – just a few feet from the kid. Although the little girl, who was born in 2003, didn't seem to mind (smoking is not a big deal in her native France), it's still rude of Olsen to subject her to dangerous second-hand smoke. Even stranger was the fact that Mary-Kate looked more like Sarkozy’s troubled teen daughter than his gal pal since the two girls, who 42-year-old Sarkozy both had his arms around during the stroll, are practically the same height, have long, dark hair, and were dressed similarly in dark clothing and funky shoes.

Olsen, 26, and Sarkozy, the financier brother of former French President Nicolas Sarkozy, have only been dating for a short time, but she is reportedly already head over heels for him. "MK is constantly complaining about boys not being mature enough for her,” a source recently told Us Weekly. “She got the kids out of her system. Now being a businesswoman dominates her time, and she is rarely impressed with guys." A second source adds, “They are good for each other.”

Before he dated Olsen, Sarkozy was in a year-long romance with actress Stella Schnabel until March. Previously, he was married to Margot’s mother, Charlotte Sarkozy, a children’s-book author and fashion writer from 1997 until 2010.
