Mary-Kate Olsen and Olivier Sarkozy, French president Nicolas Sarkozy's younger brother, are dating. It's a new relationship, but a legitimate one.
"It's true, they're dating, and she's definitely interested in him," an Olsen insider tells Us about her new romance with the 42-year-old Frenchman.
Though Olsen and Sarkozy are seventeen years apart (Olsen is 25), the source says their difference in age suits her just fine, as she's so mature.
"MK is constantly complaining about boys not being mature enough for her," the source explains. "She got the kids out of her system."
"Now being a businesswoman dominates her time, and she is rarely impressed."
Page Six broke the news of the fashion designer's newest fling on Wednesday morning; a source tells the paper the pair have together for a month.
They're "head over heels" too, apparently.
The once-divorced Sarkozy split from his last girlfriend, Stella Schnabel, in March ... On April 25, Sarkozy and Olsen attended a Knicks game together.
