Olivier Sarkozy, French-American banker and half-brother of former French President Nicolas Sarkozy, was seen Tuesday night at Zuma getting cozy with a brunette woman who was not Mary-Kate Olsen, the controversial, 26-year-old flame with whom he was seen snuggling at a Knicks game days before. According to our spy witness, Sarkozy, 42, dressed to the nines in a blue suit, was “let’s just say, more wrapped in his conversation” than he was the food. His companion, who appeared to be in her “mid 30s,” occasionally got up to go outside for a cigarette and seemed to be having a fine time. When we asked the witness if they were sure it wasn’t Olsen, who has a penchant for wearing things not intentionally meant to be disguises, we were told, “100 percent, absolutely not.” Uh-oh.

Kardashian also ate out a few times, including once with basketball wife Larsa Pippen and two other women at Prime 112, zooming away in bf Kanye West’s black Rolls Royce post-meal.
