Sharon Osbourne has come to her daughter Kelly Osbourne’s defense in her feud with Lady Gaga, ripping Gaga as “a publicity seeking hypocrite and an attention seeker” in an open letter.

The feud between Kelly and Gaga began after the “Born This Way” singer’s Little Monsters allegedly bashed the “Fashion Police” co-host over her weight.

Osbourne, who lost 50 pounds, claimed Gaga’s fans sent her death threats and vile comments. She is the daughter of rocker Ozzy Osbourne.

“I get called fat all the time. A big fat whore. 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 and ignore it,” she told Fabulous.

Osbourne’s mother, Sharon Osbourne, jumped into the fray after Gaga criticized “Fashion Police” for being too judgmental. The E! show analyzes red carpet looks of celebrities.

Sharon Osbourne wrote in her open letter to Gaga, “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,” according to TMZ.

Sharon also ripped Gaga, known as much for her unconventional attire as her singing, for wearing a dress made out of meat.

“When I see you wearing fur and you use it as a fashion statement, that defenseless animals have been killed so you can get your picture in the press is abhorrent to me,” Osbourne wrote. “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.”

Osbourne ended the scathing letter with some advice.

“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 wrote, citing Madonna, Adele and Rihanna as other Gaga victims. “A word from you would stop all this 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.”
