The former X Factor UK judge says Lady Gaga has been "hypocritical" by criticising Kelly's role on Fashion Police.

Lady Gaga and Sharon Osbourne have started a war of words online over a dispute about Kelly Osbourne's work on the E! series Fashion Police and several death threats she has received from fans of the music star.

The 'Born This Way' singer posted an open letter yesterday (10th January) after learning that several of her fans had been threatening Kelly in the wake of comments she made about the pop star, saying Kelly had taken a "less compassionate path" by presenting Fashion Police and "breeding negativity" through the message of the show.

"I have empathy for you Kelly, but I feel it culturally important to note that you have chosen a less compassionate path," Gaga writes, in her open letter posted on "Your work on E! with the Fashion Police is rooted in criticism, judgement and rating people's beauty against one another. 

"Your show breeds negativity. It glorifies you and Joan Rivers pointing in the camera, laughing and making jokes about artists and celebrities as if we are zoo animals."

The 'You & I' singer went on to criticise Kelly for mocking other celebrities after her own struggles with weight as "a youngster", and urged Kelly to set a better example for young people.

"It used to make me truly sad when I would hear people talk about your weight when you were a youngster, as I was bullied too," Gaga explained. "To see you blossoming into a beautiful slender woman who makes fun of others for a living is astounding.

"I am pointing this out not to take a crack at your character, as we've met before and you're lovely. However, I urge you to take responsibility and accountability for the example that you are setting for young people," she added.

While Kelly later posted a tweet saying she doesn't "care about any of this b******t", it was her mother Sharon who took to the internet to post an open reply to Lady Gaga, after revealing it was her who had got in touch with Gaga's management about the death threats.

Sharon started by saying she was "perplexed" to why Gaga chose to make the discussion public, and claimed the pop star's open letter was "hypocritical" and "full of contradictions".

"I don't feel I have to justify Kelly's choices in life to you," Sharon writes, later describing Gaga as "a bully". "By your actions to Kelly right now, you have shown me that you are nothing more than a publicity seeking hypocrite and an attention seeker.

"In closing, stop wearing fur, stop looking for publicity and stop using your fans to belittle not just Kelly, but an endless stream of celebrities," she finished. "Let me know if you want to continue this debate. I'm an open playing field for you my darling."

Lady Gaga has yet to respond to Sharon Osbourne's comments on the subject.
