I can't believe Rihanna missed on of her close pal's wedding, I mean if one of my friends was getting married, I would show up even if I'm not invited. Katy Perry is now offically married to Russel Brand, if Katy changes her last name it would sound weird, Katy Brand, doesn't sound right. Although I can't blame Rih for missing Katy's wedding though, she has an album coming out in a few weeks and she was in the studio all week end, sources say. So, it's really not her fault, however it's one of those things you can never really forget.
