The illustriously shirtless Trey Songz — the R&B paramour behind such bedroom jams as "Love Faces," "Neighbors Know My Name," and "I Invented Sex" — is making his movie debut this weekend in Texas Chainsaw 3D, the latest installment of the pluckily resilient horror franchise. This time, a young lady road-trips with her friends to a small Texas town to claim a mysterious inheritance from a newly discovered grandma, and — surprise! — Leatherface shows up to do some chainsaw massacrin'. Songz plays the young lady's boyfriend, and is barely in the trailer ... although he does get to drop an instantly immortal line of dialogue: "Look like Granny liked to play a little pool." And, somehow, it all makes perfect sense: There's something about the lasciviousness of Songz and the human-skin-mask-making of 'Face that just goes together. And so the primary question going forward is: Which R&B heartthrob should go the slasher flick route next? A few suggested pairings, below.
