Coolio's Pornhub Deal -- Living In A Porn Star Paradise In New Music Video

Coolio is banking on a whole lotta ass making him a player in the music biz again -- he's teamed up with a porn website for his new music video ... and it's filled with wet t-shirts, garden hoses, twerking dinosaurs ... and even Coolio.

Coolio tells TMZ ... Pornhub.com agreed to provide all the "talent" for his video -- "Take it to the Hub" -- and in exchange he's going to debut all his new music on the website.

We're told Coolio and co. banged out the vid in about 5 hours at a house in Sherman Oaks, CA. The video's pretty funny ... for some reason the director had to remind Coolio and the girls, "Smile while you're doing this. Look like you're having a good time."

This is 50-year-old Coolio's first album since 2009.

Best part of the shoot -- featuring Jessica Bangkok, Missy Martinez and Skin Diamond -- the catering was provided by the nearest El Pollo Loco.

Ay, dios mio.
