The claws are out and sharper than ever, as Kelly Osbourne's mother Sharon Osbourne has responded to Lady Gaga's open letter to her daughter. Mama O is fiercely protective of her brood, and she is showing her teeth (cue the Gaga song) with this rebuttal. She's fighting mad. It's Mother Osbourne vs. the Mother Monster.

Recap: Kelly insulted Gaga once on her show 'Fashion Police.' Kelly said Gaga's fans are the worst and call her "fat" in retaliation. Gaga wrote her an open letter regarding how Osbourne is no better since she criticizes people's looks on her show. Brilliant chess move there on Ma Monster's part.

Not so fast, though, as Sharon pulled the Furgate card, which we must admit is a valid point and a savvy move. She also told Gaga she could stop the cruelty from her fans towards Kelly in an instant.

Both letters are filled with fallacies of argument -- like Sharon saying Gaga's 32 million Twitter followers hang on her every word when half of the accounts are inactive or bot-generated.

Below is the full text of Osbourne's reply. We wonder what her husband and Kelly's father Ozzy, the Prince of Darkness, thinks of all this malarkey and mud hurling. Can't we all just get along?

Ms. Gaga,

I am responding to your open letter to my daughter Kelly, and I am perplexed as to why you would go public with an open letter. Regarding this current situation; Kelly didn’t contact you, I was the one that contacted your manager today and the email is attached below for your reference. I reached out to him as Kelly’s manager and mother to ask him if you could address your “little monster” fans and stop them from writing libelous, slanderous and vile comments about my family, including death threats to Kelly. Your open letter is hypocritical and full of contradictions. And as your mother Cynthia supports you, I support my daughter Kelly. I must say your opinions on what is politically correct and acceptable totally differ from mine, but that is what makes the world so interesting…we are all different. How sweet that you have empathy for my daughter, as you feel that she has taken a less passionate path in life. You say her work on E! with the Fashion Police is “rooted in criticism, judgment, and rating people’s beauty against one another.” Welcome to the real world. Example, when I saw you wear a dress made out of raw meat, I was sickened. When I see you wearing fur, and using it as a fashion statement, the fact that defenseless animals have been killed so you can get your picture in the press is abhorrent to me. Shouldn’t you be teaching your “little monster” fans to respect animals and life? I don’t feel I have to justify Kelly’s choices in life to you. By your actions to Kelly right now, you have shown me that you are nothing more than a publicly seeking hypocrite and an attention seeker. You know it would have been much more dignified of you to do this privately. 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?

You state “Everyday, through my music and public voice I choose to be positive and work towards a kinder and braver world with our community of followers.” Well this obviously is not translating well to your fans, as a large portion of them have not only been vile to Kelly, but also other celebrities such as Madonna, Adele and Rihanna. “You say a kinder, braver world” I don’t know what world you live in, but supporting disgraceful fan comments doesn’t fall under the words “kinder and braver.” It comes under the heading of bullshit.

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. A word from you would stop all the hideous, negative and vile threats from your “little monsters.” Let me know if you want to continue this debate. I’m an open playing field for you my darling.
