Ray J releases video for " I Hit It First " featuring Kim K look-alike

Ray J's new music video for "I Hit It First" is finally here -- and not only is the chick in the video a dead ringer for Kim Kardashian, but she also reenacts the couple's infamous sex tape (minus the sex).

Seriously, it's not an exaggeration, it's chock-full of Kim K references ... from her reality show, to her ass, to her XXX vid.

And Ray J sneaks in some Kanye shots too ... but they're a little more subtle. Kind of.
