Kelly Osbourne — who was bullied for her weight before going on Dancing With the Stars, shedding pounds and becoming a style maven on E!'s Fashion Police — recently said she still gets called fat, and worse.

"Lady Gaga’s fans are the worst," Kelly said. "They’ve said I should kill myself, that they hope I get raped. I mean it’s crazy but I’ve had this all my life and I just try and ignore it."

Mother Monster is leading a new charge against bullying, since she herself has been the victim of many weight taunts. Gaga took to her website, LittleMonsters.com, to share an open letter to Kelly, first writing that she wishes Kelly had reached out to her personally.

Here's an excerpt of the full letter:

"I have empathy for you Kelly, 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. ‘Appearance’ is the most used reason for bullying in the world. Your show breeds negativity, and over the years has even become comedic in nature. It glorifies you and Joan Rivers pointing in the camera, laughing, and making jokes about artists and celebrities as if we are zoo animals. What about your body revolution? 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. 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? I am pointing this out not to take a crack at your character, as we’ve met before and you’re lovely. However, I urge you to take responsibility and accountability for the example that you are setting for young people."

Gaga also referenced the insults Kelly received from Little Monsters.

"I cannot control my fans, and I discourage them from any negativity and violence, because that is wrong and hurtful — and I do feel [bad] that your feelings were hurt. However, we can all do our part in the media to set a standard of respect, compassion, and love. I wish for you to be treated with the kindness and respect that everyone deserves. While some of my fans have learning to do, most of them share the same values as I, and it's what bonds us together. And that bond is strong."

Mama is defending her cubs, just chiding the ones who have yet to learn not to share harsh insults and, apparently, suicide suggestions. It also sounds like Gaga is calling out Kelly on her own hypocrisy while trying to get everyone — celebs, fans, media, other — to just play nice and be compassionate instead of hurtful.
