'Fashion Police' star Kelly Osbourne has reignited her ongoing feud with modern pop icon Lady Gaga after branding the songstress a 'great big hypocrite' in a new interview.

Speaking to America's Cosmopolitan magazine, Osbourne explained that she lost respect for the 'Judas' hitmaker when she contradicted everything she stood for by letting her fans publicly send her death threats and online abuse:

"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."

The tension between them began in January when Gaga wrote an open letter to Osbourne, in which she slammed her for openly making fun of others on her 'Fashion Police' show. Sharon Osbourne then got involved, calling Gaga a bully and a bad example for trying to put herself across as an inspirational figure with her Born Brave campaign when she was being so publicly offensive.
