According to our exclusive insider, who just happens to be Kate's friend, Miz Upton met King at a party in Vegas about a year ago and since then, have hooked up at least a couple of times. Now, the two seem to be dating "casually and are just trying to have fun."
In FACT, The Other Woman star and Sports Illustrated model broke up with baseball player Justin Verlander last year to get cozier with Kev.
They may be casually dating, but it sounds like Kate really likes the idea of being King's queen. Ha!
Take another look at the two lovebirds (below)!
