Apparently Mary-Kate Olsen's boyfriend, who could be her dad, Olivier Sarkozy, recently proposed by a $350,000 12-carat marquise cut diamond ring, but she hesitated when it came to saying yes.
One of Mary-Kate's friends said she's enjoying her time with Olivier, but she is only 26 years old and is in no rush to get married.
Mary-Kate didn't want to keep the ring, but Olivier insisted, so they are calling it a "promise ring."
That is ONE expensive "promise ring." Now if that is her promise ring, Olivier will have to buy a bigger ring for the engagement ring right? HAHA! I think he just shot him self in the foot with that one!
