Kelly Osbourne has branded Lady Gaga a "big hypocrite" after the Poker Face hitmaker penned a controversial open letter to her earlier this year (13). The reality TV star claimed she had been bullied by Gaga's devoted fans, prompting the Bad Romance singer to write an online note to Osbourne in January (13) criticising her role on U.S. series Fashion Police. Gaga called on Osbourne not to make nasty comments about other people's appearances, but the letter sparked a furious response from Kelly's mother Sharon, who called the superstar an "attention seeker" and even blasted the singer on her TV panel show The Talk. Kelly addressed the drama with a simple post on her Twitter.com page telling fans she didn't care "about any of this bulls**t", but she has now opened up about the feud in a new interview with America's Cosmopolitan magazine. She says, "I loved Lady Gaga. I totally believed in everything she stood for, until I realised she's a great big hypocrite. Don't say, 'When you see bullying, intervene,' while letting your fans send me death threats. If my fans did that, I would not stand for it." "You can say whatever you want with your millions of monsters (fans). I know the truth. (Your) bells and whistles mean nothing to me. You're feeding on the freaks and geeks to further your career? Do you really care about the gay community? Because if you did, you'd stand up for it more than you do."
