Did Rihanna ditch her BFF Katy Perry's wedding?

When Katy Perry married Russell Brand in India in October, her BFF and rumored maid of honor Rihanna was a shocking no show. While Rihanna had planned on attending, she was forced to stay in L.A. to finish her new album Loud. "I'm sad that I missed it," Rihanna says. "I will never ever forgive myself for that." But Katy understood and their friendship didn't take a hit.
