Usher Paper lyrics

I heard on the radio today that the person who wrote the song Papers for Usher stated that the song is only partly true. He's claiming that all of the lyrics are not about Usher's relationship and pending divorce with his wife. Yeah , OK what ever. Oh, is it just coincidence then right? Give me a break.. This is the same thing they were claiming about Usher's Confession album. That was all about Chilly but he tried to claim it wasn't. Well I believe it was. Whats the big deal anyway. The song is hot. I dont really care who it's about.
