Jay-Z and Usher have recorded a new song together, "Best Thing" – an ode to their new status as married men. "Of course, with the talk of both of us now being newlyweds, there is a question as to why, and is it real?" Usher told MTV Base of the song, which is produced by Janet Jackson's beau Jermaine Dupri. "Well, if you hear that [song], you'll understand what [Jay-Z] meant when he says, 'Seeds becomes plants/ Boys become men/ You've got to grow up, not down.' "
