Mary Kate Olsen, Olivier Sarkozy And Other Hollywood Couples With Big Age Differences (PHOTOS)

Maybe age really is just a number.

At least that's true in Hollywood, where huge age gaps among couples are easy to come by. Still, when Mary-Kate Olsen, 26, and beau Olivier Sarkozy, 42, attended a Knicks game on Friday, the public certainly had a lot to talk about.

Despite their 17-year age difference, Olsen and Sarkozy's romance isn't the most shocking. Actor David Cross, 48, recently tied the knot with Amber Tamblyn, 29, while Hugh Hefner's girlfriend (and former fiancee) Crystal Harris is 60 years younger than him.
