Rihanna and Louis FarrakhanNation of Islam leader Minister Louis Farrakhan is famous for his outspoken ideals on politics and current events, but these days the controversial Muslim speaker has a bone to pick with an unlikely target: Rihanna.

Farrakhan, who delivered his annual Savior's Day Speech near Chicago on Sunday (Feb. 27), blasted the pop star for her scantily clad style of dress and sexually suggestive dance moves, writing her off as "filthy" and calling her fans "swine," a term which he also reserved for gays and lesbians.

Not one to keep her mouth closed, Rihanna quickly responded to Farrakhan's rants. "A minister says I perform filthy,sat+watched the filth,then called u SWINE for doin the same! Haa, Is that judgment in ur tone?" she tweeted on Monday. "I certainly don't think u are swine! But a holy man of God does!!!"
