Well if Rihanna wasn't ready I doubt she would've shot 2 or 3 videos 3 months ago, along with the album photoshoot, and released the first single in January.
And don't say "but maybe it wasn't the album shoot etc." cause Rihanna herself confirmed it on her bday.
Anyway, I still think everything was planned and I trust her as always, just hoping that the album will be out within the next 2/3 months.
