If R. Kelly does something for BRITNEY SPEARS, it will not be as boring as his songs are and it should be one of his best works. There are so many special producers to this album and it all looks perfect, so if it would suck I don't think it was on the album.
Besides the whole album sounds VERY UPTEMPO so one R&B ballad will be cool.
And I don't see why Bravo would lie about that, it's not such a story.
