Lady Gaga Hits Back At Sharon Osbourne: 'The "Real World" Can Be Cruel'

The anti anti-bullying feud continues. After Sharon Osbourne posted a scathing note reacting to Lady Gaga's open letter to daughter Kelly Osbourne last week, Gaga was compelled on Saturday to respond to the response.

"The 'real world' can be cruel, why not try to change it into a better place?," wrote Gaga on her Facebook page. "I am an activist. Nobody takes adolescents seriously, I do. My letter to Kelly Osbourne was open, because her statements on cyber-bullying were public & as a youth activist I'm compelled to be involved."

To recap: Last week, Gaga took Kelly Osbourne to task for some of the comments the singer/reality TV star has made on her E! show "Fashion Police," accusing Kelly of bullying stars about their weight and fashion choices.

"'Appearance' is the most used reason for bullying in the world," Gaga wrote. "Your show breeds negativity, and over the years has even become comedic in nature. It glorifies you and Joan Rivers pointing in the camera, laughing, and making jokes about artists and celebrities as if we are zoo animals. 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. Why not help others? Why no! t defend others who are bullied for their image and share your story?"

Sharon, who said Gaga's complaints about Kelly had led to threats against her daughter by Mother Monster's rabid fans, said she was angry that Gaga had chosen a public forum for her letter to Kelly.

"I reached out to [Gaga's manager] 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," she wrote, going on to call Gaga's letter "hypocritical and full of contradictions."

"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."
