Rihanna Forgot To Thank Calvin Harris, Performs At VMAs 2012

Rihanna opened up the MTV VMAs by performing a remix of 'Cockiness' with A$AP Rocky. Rihanna pumped up the energy by singing 'We Found Love' With Calvin Harris, which is the same song that earned Riri the top honors of the night, for Best Video of The Year. She forgot to thank Calvin, who wrote and produced the song. Calvin was quick to point it out on Twitter.
