When a story breaks that won't be covered fairly (or at all) by larger media moguls, RefinedHype DJBooth is there. When some sort of injustice or wrongdoing goes unreported, RefinedHype DJBooth is there. We are the lighthouse in the foggy, treacherous seas of internet journalism. A beacon of hope where there is only despair. If we didn't prove it with our groundbreaking absurdly detailed investigation into rapper poses we will certainly do it now.

Recently, B.o.B put Allie Haze in one of his videos. For those readers out there who don't know Haze—which judging by the speed of the booty of the week answers and the borderline unhealthy stalking of ScHoolboy's video girls is none of you—she is an adult film actress, A.K.A a porn star. Sure, putting a porn star in your music video is provocative, but that won't stop B.o.B and it certainly didn't stop these artists. It's time for an absurdly detailed investigation into porn stars in music videos.

So that's Allie Haze and Skin Diamond in one video? Hot damn! But this isn't first-time B.o.B has incorporated the use of Academy Award-winning talent in his videos. You might remember the "Headband" lyric video, which features the booties of Kristina Rose, Ava Rose and Sunny Lane, because how could you forget? Damn... five porn stars in just two videos? It looks like Bobby Ray might just be the King of Porn Star Featured Music Videos.

Not so fast, says Eminem. While you know Em for his funny, often satirical videos, Shady has also been known to put quite a few porn stars in his videos. Obviously, Lisa Ann was in the "We Made You" video because she looks just like Sarah Palin. The legendary Jenna Jameson was in the "Without Me" video and the equally as blond (though definitely less popular) Gina Lynn was in the "Superman" video. Also, I'm not sure if this counts, but Paris Hilton was in the "Just Lose It" video, and we all remember that video. But, that's not all. Apparently, Eminem spends more time on Redtube than a 14-year-old boy without parental supervision. Em also put Sasha Grey, perhaps the most famous porn star on Earth, in his "Space Bound" video. Sorry B.o.B, but I think Eminem has you beat not only in star power, but volume too; he has starred alongside more porn actresses than Ron Jeremy.

Eminem's porn star obsession also rubbed off (no pun intended) on his mentee, 50 Cent. In the "Disco Inferno" video, not just any booty would do (although there is a lot of any booty anyway), so Fiddy called on Daisy Marie to really put the booty over the edge. Also, ironically, the video features a cameo from Nick Cannon, who isn't allowed to watch porn because Mariah says so. He has to settle for BET Uncut videos.

Excessive pornstar booty in a 50 cent video is pretty much expected, but The Roots and Fall Out Boy? No way! Well, it happened; our girl Sasha Grey returns in "Birthday Girl."

We might hate on Tyga, at times, for you know... sucking (also no pun intended), but when you are making a video for a song called "Make It Nasty" he plays it perfectly. In this super-definitely NSFW video, you can find Amia Miley (and probably a handful of other porn stars I can't name) making it, indeed, nasty.

Suffering through three minutes of Tyga to see some prime booty is not exactly ideal. For those who simply can't take it, I invite you to check out Childish Gambino's "3005" lyric video. Sure the song itself is dope, but even better is that Abella Anderson is the focus. Not as naked as Tyga's video, but sometimes subtly works better (it also helps that Gambino can rap).

When filming the "We Thuggin" visuals, R. Kelly knew it would be a bad look if Fat Joe had the biggest titties in the video, so they got Tera Patrick to cameo... close enough.

So porn stars in hip-hop videos aren't as rare as we thought, but if you think it started with the likes of Fat Joe or Eminem you are dead wrong. Even before the days of internet porn (the dark ages), porn stars were still linking up with rappers for video shoots. A pioneer in the field of porn star rap videos, Tupac grabbed Nina Hartley (who is still a fox by old lady standards) and a few other (now) older porn stars for the "How Do You Want It" video; it resulted in a great video, but an even better picture.

Well, that certainly feels absurdly detailed enough. I am sure I missed some, though, but I know all the bootyologists of DJBooth Nation will fill in the blanks; y'all are a sick bunch but that's why we love you. Sometimes I have to sit back and double check that this is actually my job; this is definitely one of those times.

UPDATE: Due to popular demand, we had to do a part two, "Even More Porn Stars In Music Videos."
