Rihanna was notably absent at the 2014 Grammys when her Unapologetic album nabbed the award for Best Urban Contemporary Album.
On Tuesday's Good Morning America, the "We Found Love" singer said she was "so shocked—really" about winning a Grammy (her seventh one to date).
"I was at home and one of my friends hit me and said, 'You just won a Grammy,' and I was like, 'What?'" she said. "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."
