G-Unit

Involvement: Actors (Hosts)
Movie(s): Groupie Love (2004)
Famous co-stars: Taylor Rain, Kaylani Lei
Critical review: “All of the women are great looking, especially Monica and Kaylani. Women like this are the reason men get into music, sports, acting, law, politics or reviewing porn.” (via RogReviews)
Complex says: A few years removed from the classic G-Unit mixtape track "Porno Star," 50 and company went ahead and got into making porno films. And although G-Unit may not have many Grammys to their name, they won two AVN Awards (the Oscars of porn) for Groupie Love.
