Kelly Osbourne reignites her feud with Lady Gaga in the July issue of Cosmopolitan , on which Osbourne graces the cover.

In an interview with Cosmopolitan the host of E!’s Fashion Police called the pop star a “hypocrite” and takes a shot at Gaga’s community of followers, her little monsters.

“Don't say, 'When you see bullying, intervene,' while letting your fans send me death threats,” Osbourne said to the magazine, “If my fans did that, I would not stand for it. You can say whatever you want with your millions of monsters. I know the truth.”

The feud began in 2009 when Osbourne insulted Gaga on an episode of Fashion Police . The on-air insults culminated last year, when Osbourne took a jab at Gaga’s weight. The singer responded to Osbourne’s comment in an open letter, co-written by the Gaga’s mother, that she published on her website Little Monsters .

“I have empathy for you Kelly,” Gaga’s letter says, “But I feel it culturally important to note that you have chosen a less compassionate path. Your work on E! with the Fashion Police is rooted in criticism, judgment, and rating people's beauty against one another.”

The letter also references Osbourne’s own past struggles with weight and how she has publically fought to overcome criticism for her body.

“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,” Gaga continued. “To see you blossoming into a beautiful slender woman who makes fun of others for a living is astounding. Why not help others? Why not defend others who are bullied for their image and share your story?”

Apparently, Gaga’s olive branch of peace and “unity” was not well-received by Osbourne, who continued to bash Gaga as a role model for her fans. Osbourne also criticized the legitimacy of Gaga’s involvement with the Lesbian, Gay, Bisexual, and Transgender community.

“You [sic] bells and whistles mean nothing to me,” Osbourne said, as reported by Entertainment Weekly “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.”

Gaga has yet to respond to Osbourne’s most recent tirade, and if she is just waiting for the Fashion Police host to slip into obscurity, Osbourne assures the readers of Cosmopolitan that she will be around for a long time.

“People think this is my 15 minutes. F*%k you. I’ve got an hour.”
