Blac Chyna Stars in Belly's Music Video for 'Power of P***y'

Blac Chyna's the star in Belly's new music video ... and it is AWESOME!!!

The song is titled "P.O.P. (Power of Pussy)" and we got a clip -- yes, that's with a p. Chyna doesn't rap, but she caresses her boobs, her butt and her P while she dances next to the rapper ... and a good dancer she is.

We're told the song was not inspired by Rob -- they say it's way more universal. But here's the thing. There's a lyric, "She took you for everything, You let her do it again" and as Belly raps, Chyna winks at the camera.

Also, sorry for getting this stuck in your head. That's the P.O.P. ... the P.O.P. ...
