It’s been months since Kelly Osbourne and Lady Gaga publicly quarreled, but the “Fashion Police” star made it clear she wasn’t ready to let bygones be bygones. The former reality star called out Mother Monster for supposedly being a “great big hypocrite” in a recent interview with Cosmopolitan magazine.

Gaga has been out of the public eye for the past few months after she was forced to undergo hip surgery, but Osbourne wasn’t going to let the “Born This Way” singer’s injury get in the middle of their feud. "I loved Lady Gaga. I totally believed in everything she stood for, until I realized she's a great big hypocrite," Osbourne, 28, told the Cosmopolitan. "Don't say, 'When you see bullying, intervene,' while letting your fans send me death threats. If my fans did that, I would not stand for it." In a January interview with the U.K.’s  Fabulous magazine, the fashionista said Gaga’s fans were “the worst.” "They've said I should kill myself, that they hope I get raped," she said in reference to her critique in Gaga’s 2012 Grammys outfit.

"You can say whatever you want with your millions of monsters," Osbourne told Cosmo of the singer. "I know the truth. Your bells and whistles mean nothing to me. You're feeding on the freaks and geeks to further your career? Do you really care about the gay community? Because if you did, you'd stand up for it more than you do."

The two have been at each other’s throats for years, with their bitter battle heating up after the “Fashion Police” star’s Fabulous interview. Gaga took to her website to admonish the “less [than] compassionate” daughter of Ozzie Osbourne for “breeding negativity” on her show.

But Kelly's mother, “Talk” host Sharon, wasn’t going to let anyone bully her daughter. She wrote an open Facebook letter to Gaga and her little monsters.

"Don't let your fans be so hideously damaging, hurtful, violent ... on your website," Sharon said to the outrageous pop star. "If you are a Mother Monster, monitor it. Why haven't you, as a responsible young woman, said, 'No violence on my website, no violence, no threats, no violence.'"
