The recent pop feud between Lady Gaga and Kelly Osbourne has opened a riff between the eccentrically-wardrobed metal and pop communities. And now, fans of both artists are wondering: “Can’t we all just get along?”

It all began more than three years ago, when Ozzy’s daughter critiqued the former Stefani Germanotta’s famously unique wardrobe choices and called her a butterface.

Then last year, Kelly gave an interview in which she called Gaga’s “Little Monsters”: “The worst. They’ve said I should kill myself, and they hope that I get raped.”

The direct assaults on the chart-topping singer made Gaga retort on her personal blog. Gaga questioned the former reality star’s own body makeover, and wondered why she would accept a position on the E! Network that required her to offer up the same harsh, often cruel celebrity opinions that only a few years ago Kelly was herself a victim of. “To see you blossoming into a beautiful slender woman who makes fun of others for a living is astounding,” she wrote. A very valid point, it would seem.

But when you attack somebody, it’s only natural instinct for a mother to come out in defense of her daughter – and when said Mom is Sharon Osbourne, Ozzy’s famously outspoken wife, it’s time to strap on the body armor.

“I reached out to [your management] 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,” she wrote on her Facebook page in an open letter to Gaga. “Including death threats [they’ve made] to Kelly.”

Then, Gaga went on her Facebook page to respond to Sharon. Oh, the drama!

“The ‘real world’ can be cruel, why not try to change it into a better place?” wrote Gaga. “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, and as a youth activist I’m compelled to be involved.”
