Ri's new best seller

Rihanna's been busy in the States promoting her new book.

'Rihanna' goes behind the scenes with loads of unseen photos snapped after the release of her album Rated R and her Last Girl on Earth Tour.

Rihanna told MTV: I think it was really special to have behind-the-scenes photos, you know, pictures that the fans havent seen before, all together of a very specific moment of my life, and album of my life. They just get to see all the things that they hadnt seen that were going on behind the scenes; really cool stuff, not typical. Theyre really fun photos. And even for me, when I look at them, they say so much. Photos really tell a thousand words."

It's not only a book that Rihanna has out - her new album Loud is out on November 16th

And the 22-year-old is on the December cover of Marie Claire, here in the UK.
