So much for a detente in the Gaga-Osbourne feud.
Monday on The Talk, Sharon slammed Lady Gaga - again - for setting a bad example for her millions of fans and practicing the behavior she claims to condemn.
"Don't let your fans be so hideously damaging, hurtful, violent... on your own website," she told the singer. "If you are the Mother Monster, monitor it."
Sharon Osbourne continued, "Why haven't you, as a responsible young woman, said, 'No violence on my website, no violence, no threats, no violence.'"
Sharon also took Gaga to task for not practicing what she preaches, noting that the singer has been known to incorporate firearms into her tour act.
"Everything is guns, guns, guns," she said, citing an example in which the pop superstar wears a machine gun bra, outfitted with dueling assault rifles.
"This is not right, and she should be stopped."
"All I'm asking her to do is to stay true to her foundation, which she said [she created because] she wants the world to be a braver, kinder world," Sharon explained.
It only takes "one young person that wants attention" to start trouble, she continued, alluding to the recent school shooting in Newtown, Connecticut.
"One person wanting attention... over her not wanting to lean out to her Little Monsters to say, 'Hey guys, I love you, I understand you, [but] not everyone does."
"Please don't be violent on my site.'"
The talk-show host's on-air comments are just the latest chapter in what is shaping up to be a long and bitter battle between the Osbourne women and Gaga.
It began when Gaga posted an open letter to 28-year-old Kelly, criticizing her for insulting people for a living and basically being a bully on E!'s Fashion Police.
Sharon came to her daughter's defense a short time later with a scathing, public memo of her own, calling Gaga a hypocrite, and the feud was ignited.
"I am an activist. Nobody takes adolescents seriously, I do," Gaga wrote in response.
"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."
