Roseanne Barr: Beyonce, Jay-Z ‘Arrogant,’ Fans Are ‘Stupid’

As reported by AOL Music, when Beyonce and Jay-Z's baby daughter Blue Ivy Carter was born earlier this month, it seemed as if the whole world smiled. But there's one fellow celeb that apparently can't stand Hov and Queen B -- and isn't afraid to say so out loud!

The always outspoken, often unpleasant actress-comedienne Roseanne Barr has randomly lashed out against the power couple in a recent angry Twitter rant ... but she didn't stop there. The controversial figure also dissed Bey and Jay's fans for coming to the music couple's defense!

While "mourning" the death of legendary singer Etta James on Friday (Jan. 20), Roseanne thought it appropriate to attack President Obama for inviting Beyonce to sing Etta's classic tune 'At Last' at his 2009 Inaugural Ball, rather than the blues icon belt it out herself. "I lost ALL respect for Obama when he dissed Etta James in favor of Beyonce," she posted to her Twitter page. "I have not listened to anything Beyonce or Jay z has said or recorded since they did that to Etta. Their arrogance was disgusting," she added.

The swipe at both Beyonce and Jay, of course, caused an uproar among their fans. After receiving a barrage of angry tweets Roseanne went on to attack the music stars' fervent following, writing, "Beyonce's fans are really ignorant-she should not be proud of entertaining drooling mutants!" and "just finished telling all of beyonce's cheesy stupid a-- fans who slammed me to go and f--- themselves! It was fun!"

Eventually Roseanne retracted her statements about Beyonce being a worse singer than infamous 'American Idol' hopeful Sanjaya Malakar, but not about her and her hip-hop hubby's "disgusting arrogance." "I sincerely want2 apologize 4 the rude comments I made2 twitters defending the fabulously talented Beyonce. I reverted 2 stand up slams," she wrote.
