Heidi Klum attended the U.S. Open on Monday. Klum, 41, was there with her 28-year old art dealer boyfriend, Vito Schnabel. In the video above you see she also made sure to give some attention to what I have to assume was a friend. When I saw the ages of Klum and her boyfriend, the first thing I thought of was the Mary-Kate Olsen – Olivier Sarkozy situation at the Knicks game two years ago. After I looked up that post and found that Olsen and Sarkozy were very similar ages at the time of that Knicks game (26 and 42), I saw a picture of Klum and Olsen at the U.S. Open. And wouldn’t you know it? Mary-Kate was there with her now 45-year old fiancé, sitting a row back. Is this a very small world situation or some kind of very strange celebrity and rich person club meeting?
