CHRIS BROWN better watch his back at the Grammys on Sunday...because superstar '90s balladeer RICHARD MARX might just be "Right Here Waiting"...to BEAT HIS ASS. (???)
Marx recently added himself to Chris's long list of enemies when he Tweeted this..."Risque clothing banned at Grammys but guys who beat up women? Come ooonnn downnnnn...#goodcallgrammys."
(--Your move, Mr. Brown. Make it count, or else it "Don't Mean Nothin'"!)
