Kelly Osbourne has branded Lady GaGa a ''hypocrite''.

The 'Fashion Police' star hasn't always seen eye-to-eye with the 'Paparazzi' hitmaker after the pair clashed last year, but the feud was truly reignited after Kelly accused the singer of ''feeding'' off her army of fans, describing them as ''freaks and geeks''.

She said: ''I loved Lady Gaga. I totally believed in everything she stood for, until I realised she's a great big hypocrite.

''You're feeding on the freaks and geeks to further your career?''

The row started last year when Kelly suggested Gaga had been disrespectful to her fans - who she calls her 'Little Monsters' - for skipping the red carpet at the Grammy Awards, which prompted them to send Kelly death threats via social media.

Kelly then continued the arguement later in the year when she suggested the 'Born This Way' singer was pregnant due to a clothing choice on a TV talk show, and Gaga hit back saying the 28-year-old star should ''defend others who are bullied for their image''.

Kelly ranted: ''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. I know the truth. [Your] bells and whistles mean nothing to me.''
