Kelly Osbourne slammed Lady Gaga for being a "great big hypocrite" in a recent interview this week.
The jab at the "Born This Way" singer arrives after a long feud began in early 2012 when Osbourne criticized Gaga for not appearing on the Grammys red carpet, prompting the singer to fight back on Twitter.
Today, Osbourne explained her view that Gaga is a hypocrite when it comes to issues such as bullying.
"I loved Lady Gaga, I totally believed in everything she stood for, until I realized that she's a great big hypocrite," the "Fashion Police" star told Cosmopolitan magazine.
"Don't say, 'When you see bullying, intervene,' while letting your fans send me death threats," Osbourne continued. "If my fans did that, I would not stand for it."
Furthermore, the daughter of Ozzy Osbourne referenced the dedicated fans of lady Gaga who identify themselves as "monsters."
"You can say whatever you want with your millions of monsters," said Osbourne. "I know the truth. [Your] bells and whistles mean nothing to me."
The 28-year-old also questioned Lady Gaga's motives for siding with certain groups such as the lesbian, gay, bisexual and transgender (LGBT) community during the interview.
"You're feeding 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," said Osbourne, seeming to directly address Gaga via the July edition of Cosmo.
Osbourne's comments stem from the feud with Gaga that also included the singer deeming "Fashion Police" a show that "breeds negativity" in an open letter.
Gaga also told Osbourne that she should "defend others who are bullied for their image" in the letter.
Meanwhile, Osbourne is still over her father's admission of relapsing into drugs.
"I love and respect that he's honest enough to say, 'Yes, I did this. It was my fault.' He's a real man," Osbourne said of her father Ozzy.
"Most people would hide, and he doesn't," she added. "It doesn't make me love him any less. It took a long time to get to that place, but I understand it now. And my mother does, too."
