Kim Kardashian and Reggie Bush were spotted yesterday leaving the Le Parker Meridian Hotel here in NYC. Last night, Kim tweeted that they were in town to do Jimmy Fallon and the show should be airing soon. There has been a buzz around the web that these two are now engaged, but if they are, they are definitely keeping it on the low. Kim hasn't been rocking a ring, and there has been no announcement of it yet. They do, however, seem to be enjoying each other and spending a lot of quality time.
