I came across this article while surfing recently and it dawned on me that this could be a great match-up. I can picture the two "power couples" from there respective genre's getting together for a Dinner party at one of the couples many mansions and Tim Mcgraw and Jay Z being the competetive "Alpha males" that they are decide to put a little wager on who's beautiful wife would come out on top in a catfight. Pitting the tall,blonde and slender Faith up against the shorter but more curvaceous Beyonce.
This just seems like a really intriguing story-line to me especially with the whole contrasting "country vs hip-hop" angle. I would take a stab at writing it myself if I had more time. I just thought if one of the many talented writers around here was looking for something to get there "juices flowing" they might decide to give it a go.

Forbes magazine calls Tim McGraw & Faith Hill the "Jay-Z & Beyonce of country music"
