Rihanna has said she was 'so shocked' to win the Grammy Award for Best Urban Contemporary Album.

The singer won the Grammy for her 2012 album Unapologetic and she told Good Morning America, "I was so shocked. Really, I was at home and one of my friends hit me and said, 'You've just won a Grammy', and I was like, 'What?' and when I went on the internet I just saw Unapologetic.

"It was quite an emotional moment surprisingly. But I was in shock, I'm excited, it was a good feeling to still be that excited at this point in my career."
