As I told you in the #MaddHouse, Russell Brand has officially #unfollowed his ex-wife Katy Perry!

Rihanna, unhappy with ex Chris Brown's lyrics, unfollowed him on Twitter! Apparently he knew what he did with this tweet, "Assumptions, I didn't say any names so if you took offense to it then it's something you feel guilty about!" So Rihanna, apparently along with Russel Brand is giving their ex partners the 2012 Ultimate Diss, #Unfollowed!
