Madison Square Garden is quickly emerging as Mary Kate Olsen and Olivier Sarkozy’s favorite place to make out. The power-sibling pair were spotted canoodling at the Knicks game last night, in a nearly exact replica of November’s display. The only difference is this time Mary-Kate Olsen is wearing a ring. And we have no choice but to wonder whether they find basketball games thrilling for, um, different reasons than we do. Sorry, guy sitting in front of them.
