Rihanna says it was simply work that prevented her from attending the wedding, as she's prepping for the release of her new album, Loud, and needed to be available to make any last-minute decisions.

Still, Rihanna says she was totally bummed that wasn't able to support Perry as she said "I do" to Russell Brand.
