Sharon Osbourne Weighs In On The Feud Between Daughter Kelly And Lady Gaga

And the fighting continues!

Kelly Osbourne has been engaged in a very public war of words with Lady Gaga recently, and now mom Sharon is speaking her mind on the cat fight.

Kelly O has taken shots at the pop star for years, first calling her a "Butterface" in 2009, then slamming her weight in September, saying, "I think she is pregnant." It is the British beauty's obligation to critique celebrities and their outfits for her hosting job on Fashion Police, but the "Born This Way" singer's fans aren't having it!

Millions of "Little Monsters" have been posting horrible things on social media about Osbourne, who spoke out about the cruelty in Fabulous magazine last October, saying, "Lady Gaga's fans are the worst. They've said I should kill myself, that they hope I get raped. I mean it's crazy but I've had this all my life and I just try to ignore it."

Gaga replied by posing an open letter to Osbourne on her blog Thursday.

"I have empathy for you Kelly, but I feel it culturally important to note that you have chosen a less compassionate path. Your work on E! with the Fashion Police is rooted in criticism, judgment, and rating people's beauty against one another... What about your body revolution? It used to make me truly sad when I would hear people talk about your weight when you were younger, as I was bullied too. To see you blossoming into a beautiful slender woman who makes fun of others for a living is astounding," she wrote.

The America's Got Talent judge is now coming to her daughter's defense, calling on Gagaloo's manager to urge the Grammy winner to dissuade her fans from all of their bullying.

"Your open letter is hypocritical and full of contradictions. And as your mother Cynthia supports you, I support my daughter Kelly. I am calling you a bully because you have 32 million followers hanging on your every word and you are criticizing Kelly in your open letter. Are you so desperate that you needed to make this public? A word from you will stop all the hideous, negative, and vile threats from your 'little monsters'" the family matriarch posted to her Facebook page.

Your move, Mother Monster!
